Ibn Jonayd Eskafi

Ibn al-Junayd al-Eskafi (ابن الجنيد الاسکافی) was one of the first eminent Shi'a jurists during the fourth century lunar hijrah.

Early life
Abu Ali Muhammad ibn Ahmad Katib Iskafi (tenth century AD/fourth century lunar) was born in Iskaf, a region near Nahrawan Canal in Iraq. His date of birth is uncertain. He may have traveled to Nishapur. He may have visited Muhammed Ibn Hosein Alavi. According to Shaykh Mufid's sayings, it seems that Ibn Jonayd passed most of his life in Baghdad. He may have had communication with the twelfth Imam.

Jurisprudence
He took a different approach in understanding Shia traditions. He believed in a theological basis for interpretation of Hadith. He believed that we must commit to Khabar Vahed and Qyas in jurisprudence. He acted like antecedent jurists such as Fazl ibn Shazan and Younes ibn Abdul Rahman. One of his characteristics in Fiqh discussion was that he believed to Ihtiyat (probability) approximately in most problems. in other words, the principle of Ihtiyyat is prevalent in his juridical works. He employed other ideas in shia jurisprudence such as:
 * Acting according to reason and justification
 * Clarity in explaining the reason for a judgment
 * Establish dynamic basic for shia jurisprudence

Works
He had special skill in writing and became known as Katib by scholars. He wrote nearly in all Islamic sciences, particularly jurisprudence, theology and apologetics, such as: He also wrote about the art of writing: Ilm Al Nijabah Fi Ilm Al Kitabah and Al Tahrir va Taqrir.
