Al-Ghazali

Abū Ḥāmid Muḥammad ibn Muḥammad al-Ṭūsiyy al-Ghazali (أَبُو حَامِد مُحَمَّد بْن مُحَمَّد ٱلطُّوسِيّ ٱلْغَزَّالِيّ), known commonly as Al-Ghazali (ٱلْغَزَالِيُّ;, ; c. 1058 – 19 December 1111), known in Medieval Europe by the Latinized Algazelus or Algazel, was a Persian Sunni Muslim polymath. He is known as one of the most prominent and influential jurisconsults, legal theoreticians, muftis, philosophers, theologians, logicians and mystics in Islamic history.

He is considered to be the 11th century's mujaddid, a renewer of the faith, who, according to the prophetic hadith, appears once every 100 years to restore the faith of the Islamic community. Al-Ghazali's works were so highly acclaimed by his contemporaries that he was awarded the honorific title "Proof of Islam" (Ḥujjat al-Islām). Al-Ghazali was a prominent mujtahid in the Shafi'i school of law.

Much of Al-Ghazali's work stemmed around his spiritual crises following his appointment as the head of the Nizzamiyya University in Baghdad - which was the most prestigious academic position in the Muslim world at the time. This led to his eventual disappearance from the Muslim world for over 10 years, realising he chose the path of status and ego over God. It was during this period where many of his great works were written. He believed that the Islamic spiritual tradition had become moribund and that the spiritual sciences taught by the first generation of Muslims had been forgotten. This belief led him to write his magnum opus entitled Iḥyā’ ‘ulūm ad-dīn ("The Revival of the Religious Sciences"). Among his other works, the Tahāfut al-Falāsifa ("Incoherence of the Philosophers") is a landmark in the history of philosophy, as it advances the critique of Aristotelian science developed later in 14th-century Europe.

Biography
Al-Ghazali was born in c. 1058 in Tus, then part of the Seljuk Empire. He was a Muslim scholar, law specialist, rationalist, and spiritualist of Persian descent. He was born in Tabaran, a town in the district of Tus, Khorasan (now part of Iran), not long after Seljuks entered Baghdad and ended Shia Buyid Amir al-umaras. This marked the start of Seljuk influence over Caliphate. While the Seljuk dynasty's influence grew, Abu Suleiman Dawud Chaghri Beg married his daughter, Arslan Khatun Khadija to caliph al-Qa'im in 1056.

A posthumous tradition, the authenticity of which has been questioned in recent scholarship, is that his father died in poverty and left the young al-Ghazali and his brother Ahmad to the care of a Sufi. Al-Ghazali's contemporary and first biographer, 'Abd al-Ghafir al-Farisi, records merely that al-Ghazali began to receive instruction in fiqh (Islamic jurisprudence) from Ahmad al-Radhakani, a local teacher and Abu ali Farmadi, a Naqshbandi sufi from Tus. He later studied under al-Juwayni, the distinguished jurist and theologian and "the most outstanding Muslim scholar of his time," in Nishapur, perhaps after a period of study in Gurgan. After al-Juwayni's death in 1085, al-Ghazali departed from Nishapur and joined the court of Nizam al-Mulk, the powerful vizier of the Seljuk empire, which was likely centered in Isfahan. After bestowing upon him the titles of "Brilliance of the Religion" and "Eminence among the Religious Leaders", Nizam al-Mulk advanced al-Ghazali in July 1091 to the "most prestigious and most challenging" professorial position at the time: the Nizamiyya madrasa in Baghdad.

He underwent a spiritual crisis in 1095, which some speculate was brought on by clinical hysteria,  abandoned his career and left Baghdad on the pretext of going on pilgrimage to Mecca. Making arrangements for his family, he disposed of his wealth and adopted an ascetic lifestyle. According to biographer Duncan B. Macdonald, the purpose of abstaining from scholastic work was to confront the spiritual experience and more ordinary understanding of "the Word and the Traditions." After some time in Damascus and Jerusalem, with a visit to Medina and Mecca in 1096, he returned to Tus to spend the next several years in uzla (seclusion). The seclusion consisted in abstaining from teaching at state-sponsored institutions, but he continued to publish, receive visitors and teach in the zawiya (private madrasa) and khanqah (Sufi lodge) that he had built.

Fakhr al-Mulk, grand vizier to Ahmad Sanjar, pressed al-Ghazali to return to the Nizamiyya in Nishapur. Al-Ghazali reluctantly capitulated in 1106, fearing rightly that he and his teachings would meet with resistance and controversy. He later returned to Tus and declined an invitation in 1110 from the grand vizier of the Seljuq Sultan Muhammad I to return to Baghdad. He died on 19 December 1111. According to 'Abd al-Ghafir al-Farisi, he had several daughters but no sons.

School affiliations
Al-Ghazali contributed significantly to the development of a systematic view of Sufism and its integration and acceptance in mainstream Islam. As a scholar of Islam, he belonged to the Shafi'i school of Islamic jurisprudence and to the Asharite school of theology. Al-Ghazali received many titles such as Zayn al-Dīn (زين الدين) and Ḥujjat al-Islām (حجة الإسلام).



He is viewed as the key member of the influential Asharite school of early Muslim philosophy and the most important refuter of the Mutazilites. However, he chose a slightly different position in comparison with the Asharites. His beliefs and thoughts differ in some aspects from the orthodox Asharite school.

Works
A total of about 70 works can be attributed to al-Ghazali. He is also known to have written a fatwa against the Taifa kings of al-Andalus, declaring them to be unprincipled, not fit to rule and that they should be removed from power. This fatwa was used by Yusuf ibn Tashfin to justify his conquest of al-Andalus.

Incoherence of the Philosophers
Al-Ghazali's 11th century book titled Tahāfut al-Falāsifa ("Incoherence of the Philosophers") marked a major turn in Islamic epistemology. The encounter with skepticism led al-Ghazali to investigate a form of theological occasionalism, or the belief that all causal events and interactions are not the product of material conjunctions but rather the immediate and present will of God.

In the next century, Ibn Rushd (or Averroes) drafted a lengthy rebuttal of al-Ghazali's Incoherence entitled The Incoherence of the Incoherence; however, the epistemological course of Islamic thought had already been set. Al-Ghazali gave as an example of the illusion of independent laws of cause the fact that cotton burns when coming into contact with fire. While it might seem as though a natural law was at work, it happened each and every time only because God willed it to happen—the event was "a direct product of divine intervention as any more attention grabbing miracle". Averroes, by contrast insisted while God created the natural law, humans "could more usefully say that fire caused cotton to burn—because creation had a pattern that they could discern."

The Incoherence also marked a turning point in Islamic philosophy in its vehement rejections of Aristotle and Plato. The book took aim at the Falāsifa, a loosely defined group of Islamic philosophers from the 8th through the 11th centuries (most notable among them Avicenna and al-Farabi) who drew intellectually upon the Ancient Greeks.

The influence of Al-Ghazali's book is still debated. Professor of Arabic and Islamic Science George Saliba in 2007 argued that the decline of science in the 11th century has been overstated, pointing to continuing advances, particularly in astronomy, as late as the 14th century.

Professor of Mathematics Nuh Aydin wrote in 2012 that one the most important reasons of the decline of science in the Islamic world has been Al-Ghazali's attack of philosophers (scientists, physicists, mathematicians, logicians). The attack peaked in his book Incoherence, whose central idea of theological occasionalism implies that philosophers cannot give rational explanations to either metaphysical or physical questions. The idea caught on and nullified the critical thinking in the Islamic world.

On the other hand, author and journalist Hassan Hassan in 2012 argued that while indeed scientific thought in Islam was stifled in the 11th century, the person mostly to blame is not al-Ghazali but Nizam al-Mulk.

The Revival of Religious Sciences (Ihya' Ulum al-Din)
Another of al-Ghazali's major works is Ihya' Ulum al-Din or Ihya'u Ulumiddin (The Revival of Religious Sciences). It covers almost all fields of Islamic sciences: fiqh (Islamic jurisprudence), kalam (theology) and sufism.

It contains four major sections: Acts of worship (Rub' al-'ibadat), Norms of Daily Life (Rub' al-'adatat), The ways to Perdition (Rub' al-muhlikat) and The Ways to Salvation (Rub' al-munjiyat). The Ihya became the most frequently recited Islamic text after the Qur'an and the hadith. Its great achievement was to bring orthodox Sunni theology and Sufi mysticism together in a useful, comprehensive guide to every aspect of Muslim life and death. The book was well received by Islamic scholars such as Nawawi who stated that: "Were the books of Islam all to be lost, excepting only the Ihya', it would suffice to replace them all."

The Alchemy of Happiness
The Alchemy of Happiness is a rewritten version of The Revival of the Religious Sciences. After the existential crisis that caused him to completely re-examine his way of living and his approach to religion, al-Ghazali put together The Alchemy of Happiness.

Disciplining the Soul
One of the key sections of Ghazali's Revival of the Religious Sciences is Disciplining the Soul, which focuses on the internal struggles that every Muslim will face over the course of his lifetime. The first chapter primarily focuses on how one can develop himself into a person with positive attributes and good personal characteristics. The second chapter has a more specific focus: sexual satisfaction and gluttony. Here, Ghazali states that indeed every man has these desires and needs, and that it is natural to want these things. However, the Prophet explicitly states that there must be a middle ground for man, in order to practice the tenets of Islam faithfully. The ultimate goal that Ghazali is presenting not only in these two chapters, but in the entirety of The Revival of the Religious Sciences, is that there must be moderation in every aspect of the soul of a man, an equilibrium. These two chapters were the 22nd and 23rd chapters, respectively, in Ghazali's Revival of the Religious Sciences.

The Eternity of the World
Al-Ghazali crafted his rebuttal of the Aristotelian viewpoint on the creation of the world in The Eternity of the World. Al-Ghazali essentially formulates two main arguments for what he views as a sacrilegious thought process. Central to the Aristotelian approach is the concept that motion will always precede motion, or in other words, a force will always create another force, and therefore for a force to be created, another force must act upon that force. This means that in essence time stretches infinitely both into the future and into the past, which therefore proves that God did not create the universe at one specific point in time. Al-Ghazali counters this by first stating that if the world was created with exact boundaries, then in its current form there would be no need for a time before the creation of the world by God.

The Decisive Criterion for Distinguishing Islam from Clandestine Unbelief
Al-Ghazali lays out in The Decisive Criterion for Distinguishing Islam from Clandestine Unbelief his approach to Muslim orthodoxy. Ghazali veers from the often hardline stance of many of his contemporaries during this time period and states that as long as one believes in the Prophet Muhammad and God himself, there are many different ways to practice Islam and that any of the many traditions practiced in good faith by believers should not be viewed as heretical by other Muslims. While Ghazali does state that any Muslim practicing Islam in good faith is not guilty of apostasy, he does outline in The Criterion that there is one standard of Islam that is more correct than the others, and that those practicing the faith incorrectly should be moved to change. In Ghazali's view, only the Prophet himself could deem a faithfully practicing Muslim an infidel, and his work was a reaction to the religious persecution and strife that occurred often during this time period between various Islamic sects.

Deliverance from Error


The autobiography al-Ghazali wrote towards the end of his life, Deliverance From Error (المنقذ من الضلال al-Munqidh min al-Dalal), is considered a work of major importance. In it, al-Ghazali recounts how, once a crisis of epistemological skepticism had been resolved by "a light which God Most High cast into my breast ... the key to most knowledge," he studied and mastered the arguments of kalam, Islamic philosophy, and Ismailism. Though appreciating what was valid in the first two of these, at least, he determined that all three approaches were inadequate and found ultimate value only in the mystical experience and insight he attained as a result of following Sufi practices. William James, in Varieties of Religious Experience, considered the autobiography an important document for "the purely literary student who would like to become acquainted with the inwardness of religions other than the Christian" because of the scarcity of recorded personal religious confessions and autobiographical literature from this period outside the Christian tradition.

Works in Persian
Al-Ghazali wrote most of his works in Persian and in Arabic. His most important Persian work is Kimiya-yi sa'adat (The Alchemy of Happiness). It is al-Ghazali's own Persian version of Ihya' 'ulum al-din (The Revival of Religious Sciences) in Arabic, but a shorter work. It is one of the outstanding works of 11th-century-Persian literature. The book was published several times in Tehran by the edition of Hussain Khadev-jam, a renowned Iranian scholar. It is translated to English, Arabic, Turkish, Urdu, Azerbaijani and other languages.

Another authentic work of al-Ghazali is the so-called "first part" of the Nasihat al-muluk (Counsel for kings), addressed to the Saljuqid ruler of Khurasan Ahmad b. Malik-shah Sanjar (r. 490-552/1097-1157). The text was written after an official reception at his court in 503/1109 and upon his request. Al-Ghazali was summoned to Sanjar because of the intrigues of his opponents and their criticism of his student's compilation in Arabic, al-Mankhul min taʿliqat al-usul (The sifted notes on the fundamentals), in addition to his refusal to continue teaching at the Nizamiya of Nishapur. After the reception, al-Ghazali had, apparently, a private audience with Sanjar, during which he quoted a verse from the Quran 14:24: "Have you not seen how Allah sets forth a parable of a beautiful phrase (being) like a beautiful tree, whose roots are firm and whose branches are in Heaven." The genuine text of the Nasihat al-muluk, which is actually an official epistle with a short explanatory note on al-Manḵul added on its frontispiece.

The majority of other Persian texts, ascribed to him with the use of his fame and authority, especially in the genre of Mirrors for Princes, are either deliberate forgeries fabricated with different purposes or compilations falsely attributed to him. The most famous among them is Ay farzand (O Child!). This is undoubtedly a literary forgery fabricated in Persian one or two generations after al-Ghazali's death. The sources used for the forgery consist of two genuine letters by al-Ghazali's (number 4, in part, and number 33, totally); both appear in the Fazaʾil al-anam. Another source is a letter known as ʿAyniya and written by Muhammad's younger brother Majd al-Din Ahmad al-Ghazali (d. 520/1126) to his famous disciple ʿAyn al-Quzat Hamadani (492-526/1098-1131); the letter was published in the Majmuʿa-yi athar-i farsi-yi Ahmad-i Ghazali (Collection of the Persian writings of Ahmad Ghazali). The other is ʿAyn al-Quzat's own letter, published in the Namaha-yi ʿAyn al-Quzat Hamadani (Letters by ʿAyn al-Quzat Hamadani). Later, Ay farzand was translated into Arabic and became famous as Ayyuha al-walad, the Arabic equivalent of the Persian title. The earliest manuscripts with the Arabic translation date from the second half of the 16th and most of the others from the 17th century. The earliest known secondary translation from Arabic into Ottoman Turkish was done in 983/1575. In modern times, the text was translated from Arabic into many European languages and published innumerable times in Turkey as Eyyühe'l-Veled or Ey Oğul.

A less famous Pand-nama (Book of counsel) also written in the genre of advice literature is a very late compilatory letter of an unknown author formally addressed to some ruler and falsely attributed to al-Ghazali, obviously because it consists of many fragments borrowed mostly from various parts of the Kimiya-yi saʿadat.

Influence
During his life, Al-Ghazali wrote over 70 books on science, Islamic reasoning and Sufism. Al-Ghazali played a major role in integrating Sufism with Shariah. He was also the first to present a formal description of Sufism in his works. His works also strengthened the status of Sunni Islam against other schools. The Batinite (Ismailism) had emerged in Persian territories and were gaining more and more power during al-Ghazali's period, as Nizam al-Mulk was assassinated by the members of Ismailis. In his Fada'ih al-Batiniyya (The Infamies of the Esotericists) al-Ghazali declared them unbelievers whose blood may be spilled. Al-Ghazali succeeded in gaining widespread acceptance for Sufism at the expense of philosophy. At the same time, in his refutation of philosophers he made use of their philosophical categories and thus helped to give them wider circulation.

The staple of his religious philosophy was arguing that the creator was the center point of all human life that played a direct role in all world affairs. Al-Ghazali's influence was not limited to Islam, but in fact his works were widely circulated among Christian and Hebrew scholars and philosophers. Some of the more notable philosophers and scholars in the west include David Hume, Dante, and St. Thomas Aquinas. Moses Ben Maimon, a Jewish theologian was deeply interested and vested in the works of al-Ghazali. One of the more notable achievements of Ghazali were his writing and reform of education that laid the path of Islamic Education from the 12th to the 19th centuries. Al-Ghazali's works were heavily relied upon by Islamic mathematicians and astronomers such as At-Tusi.

Al-Ghazali was by every indication of his writings a true mystic in the Persian sense. He believed himself to be more mystical or religious than he was philosophical however, he is more widely regarded by some scholars as a leading figure of Islamic philosophy and thought. He describes his philosophical approach as a seeker of true knowledge, a deeper understanding of the philosophical and scientific, and a better understanding of mysticism and cognition. The period following Ghazali "has tentatively been called the Golden Age of Arabic philosophy" initiated by Ghazali's successful integration of logic into the Islamic seminary Madrasah curriculum.

Imam Al Ghazali mainly chose to keep his legacy in his books so he wrote more than 70 books in his career. It is said about his book "Ihya Ulum Uddin: The Revival of the Religious Sciences" that, if one has no Shaykh Then he has Ihya. Through his writing he still influences islamic scholars and community. Prominent scholars like Shaykh Hamza Yusuf, Shaykh Ibrahim Osi Efa, Dr. Abdul Hakim Murad (Timothy Winter) is greatly influenced by his teaching. People refer to him as the "Proof of Islam".

Number of works
Al-Ghazali mentioned the number of his works "more than 70" in one of his letters to Sultan Sanjar in the late years of his life. Some "five dozen" are plausibly identifiable, and several hundred attributed works, many of them duplicates because of varying titles, are doubtful or spurious.

The tradition of falsely attributing works to al-Ghazali increased in the 13th century, after the dissemination of the large corpus of works by Ibn Arabi.

Bibliographies have been published by William Montgomery Watt (The Works Attributed to Al-Ghazali), Maurice Bouyges (Essai de chronologie des oeuvres d'Al-Ghazali) and others.

Economic philosophy
Al-Ghazali's economic philosophy was primarily influenced by his Islamic beliefs. He argued that the importance of economic activity lay both in its benefit to society, as well being necessary for salvation.

He established three goals of economic activity that he believed were part of one's religious obligation: "achievement of self-sufficiency for one's survival; provision for the well-being of one's progeny; and provision for assisting those in economic need." He argued that subsistence living, or living in a way that provides the basic necessities for only one's family, would not be an acceptable practice to be held by the general population because of the detrimental results that he believed that would bring upon the economy, but he acknowledged that some people may choose to live the subsistence lifestyle at their own will for the sake of their personal religious journey. Conversely, he discouraged people from purchasing or possessing excessive material items, suggesting that any additional money earned could be given to provide for the poor.

Al-Ghazali believed that the imposition of income equality in society should not be a necessity. Instead, he advocated for individuals to be guided by the "spirit of Islamic brotherhood," encouraging them to willingly share their wealth. However, he acknowledged that this ideal isn't universally practiced. According to him, earned wealth can serve two potential purposes. The first is for the good of oneself, which includes maintaining one's own health and that of their family, as well as extending care to others and engaging in actions beneficial to the Islamic community. The other is what al-Ghazali would consider misuse, spending it selfishly on extravagant or unnecessary material items.

In terms of trade, al-Ghazali discussed the necessity of exchanging goods across close cities as well as larger borders because it allows more goods, which may be necessary and not yet available, to be accessible to more people in various locations. He recognized the necessity of trade and its overall beneficial effect on the economy, but making money in that way might not be considered the most virtuous in his beliefs. He did not support people taking "excessive" profits from their trade sales.

Reception of work
According to William Montgomery Watt, al-Ghazali was considered to be the mujaddid ("Reviver") of his age. Many, perhaps most, later Muslims concurred and, according to Watt, some have even considered him to be the greatest Muslim after Muhammad.

As an example, the Islamic scholar al-Safadi stated: Muhammad ibn Muhammad ibn Muhammad ibn Ahmad, the Proof of Islam, Ornament of the Faith, Abu Hamid al-Tusi (al-Ghazali) the Shafi'ite jurist, was in his later years without rival.

and the jurist, al-Yafi'i stated:

He was called The Proof of Islam and undoubtedly was worthy of the name, absolutely trustworthy (in respect of the Faith) How many an epitome (has he given) us setting forth the basic principles of religion: how much that was repetitive has he summarised, and epitomised what was lengthy. How many a simple explanation has he given us of what was hard to fathom, with brief elucidation and clear solution of knotty problems. He used moderation, being quiet but decisive in silencing an adversary, though his words were like a sharp sword-thrust in refuting a slanderer and protecting the high-road of guidance.

The Shafi'i jurist al-Subki stated:

"If there had been a prophet after Muhammad, al-Ghazali would have been the man".

Also a widely considered Sunni scholar, al-Dhahabi, in his praise of al-Ghazali wrote: "Al-Ghazzaali, the imaam and shaykh, the prominent scholar, Hujjat al-Islam, the wonder of his time, Zayn al-Deen Abu Haamid Muhammad ibn Muhammad ibn Muhammad ibn Ahmad al-Toosi al-Shaafa'i al-Ghazzaali, the author of many books and one possessed of utter intelligence. He studied fiqh in his own town, then he moved to Nisapur in the company of a group of students. He stayed with the Imaam al-Haramayn and gained a deep knowledge of fiqh within a short period. He became well-versed in 'ilm al-kalaam and debate, until he became the best of debater."

Ibn Rushd (Averroes), a rationalist, famously responded that "to say that philosophers are incoherent is itself to make an incoherent statement." Rushd's book, The Incoherence of the Incoherence, attempted to refute al-Ghazali's views, but the work was not well received in the Muslim community.

According to historian Firas Alkhateeb, "When one reads Imam al-Ghazali's works at a very superficial level, one can easily misunderstand what he is saying as anti-scientific in general. The truth, however, is that al-Ghazali's only warning to students is to not fully accept all the beliefs and ideas of a scholar simply because of his achievements in mathematics and science. By issuing such a warning, al-Ghazali is in fact protecting the scientific enterprise for future generations by insulating it from being mixed with theoretical philosophy that could eventually dilute science itself to a field based on conjecture and reasoning alone."

Al-Ghazali has been seen by Orientalist scholars as causing a decline in scientific advancement in Islam, because of his refutation of the new philosophies of his time. He purportedly saw danger in the statements made by philosophers that suggested that God was not all-knowing or even non-existent, which strongly contradicted his conservative Islamic belief. This position has been challenged, however. The following statement made by al-Ghazali has been described as evidence that he was not against scientific advancement: "Great indeed is the crime against religion committed by anyone who supposes that Islam is to be championed by the denial of mathematical sciences." This sentence, the source of which is not indicated in the cited book, is taken from Deliverance from Error. Ghazali does not mean that neglecting the study of mathematics would be a crime against science or against reason, but that rejecting them is a crime against religion. Its aim is not to promote the study of mathematics: it is to condemn the attitude which consists in considering them as rivals of religion. For him, religion has nothing to fear from them, because they do not deal with the same subjects. To condemn the study of mathematics for fear that it endangers religion is to mistake the place of each of them. This is clarified by the sentence which immediately follows: "For the revealed Law nowhere undertakes to deny or affirm these sciences, and the latter nowhere address themselves to religious matters. " A few pages later, he writes that the books of the philosophers must be banned - he defines philosophy as composed of six branches: mathematical, logical, physical, metaphysical, political, and morale. Al-Ghazali notably influenced Ibn Rushd, Ayn al-Quzat Hamadani, al-Nawawi, Ibn Tumart, Fakhruddin Razi, Suyuti, Tan Malaka, Thomas Aquinas, David Hume, Sayf al-Din al-Amidi, Asad Mayhani, Ali al-Qari, Muhammad Ibn Yahya al-Janzi.
