Sujud

Sujūd (سُجود, ), or sajdah (سجدة, ), also known as sijda, sejda or shejda is the act of low bowing or Prostration to (God) facing the qiblah (direction of the Kaaba at Mecca). It is usually done in standardized prayers (salah). The position involves kneeling and bowing till one touches the ground with 7 bones (points): the forehead & nose, two hands, two knees and two sets of toes. In accordance with the Sunnah (the Way) of Muhammad, one's elbows should be far from one's body, unless it causes discomfort to other worshippers. Some scholars hold the position that this applies only to men, and that women are encouraged to tuck their elbows in out of modesty,

Overview
Sujud (prostration) is one of the main pillars of daily prayer in Islam. A single act of sujud is called a sajdah (plural sajdāt). Muslims do sujud several times in each prayer, depending on the number of raka'at of prayer: two sajadat are performed every raka'ah, and prayers vary in obligatory length between two and four raka'at (additional supererogatory raka'at are often performed as sunnah muakkadah, or emulation of the example of Muhammad as represented in the sahih hadith). A raka'ah is a unit of set actions that have to be performed in a prayer. The shortest fard (obligatory) Muslim prayer is that of fajr, performed immediately before sunrise (2 raka'ahs) and the shortest ever possible number of raka'ahs is in the Witr prayer, which is considered Sunnah in the Maaliki, Shafi'i and Hanbali Madhabs (Schools of Fiqh) and Wajib (Compulsory) in the Hanafi madhab, with one needing an odd number of Rakats to complete the prayer, with 1 being valid in all madhabs but the Hanafi Madhab. The raka'ah can be described as follows:

Points 1-7 define one raka'ah. Thus, the shortest prayer, that of fajr, contains four sajadat. For Hanafis, witr prayer is three raka'ahs, which is for them considered wajib, a level of necessity below that of fard but above all else: in practice, this makes witr obligatory.
 * 1) Standing and saying Allahu akbar, reciting surah al-Fatiha, and reciting a short passage of the Quran such as sura al-Ikhlas.
 * 2) Performing ruku' (bowing down) without bending the knees and with hands resting on the knees, while reciting additional phrases to glorify Allah.
 * 3) Standing up from bowing, and reciting further.
 * 4) Going in prostration (sajdah) once, while reciting additional specific phrases to glorify Allah.
 * 5) Lifting the face up from prostration but kneeling or sitting on the ground.
 * 6) Performing a second prostration (sajdah).
 * 7) Rising for the second, third, or fourth raka'ah. In the last raka'ah, one remains sitting and recites the tashahhud, and then performs the taslim by turning the head to the right and saying, as-salamu alaikum wa rahmatu Allah wa barakatuh ("may the peace, mercy, and blessings of God be upon you"), and then turning the head to the left and repeating the blessing to conclude the prayer.

While in sujud, the use of a turbah (a small piece of soil or clay, often a clay tablet), on which a person places their forehead, is compulsory in most Shi'a schools of Islam.

Sajdah of recitation / Tilawah
During recitation (tilawa) of the Qur'an, including individual and congregation prayers, there are fifteen places where Muslims believe, when Muhammad recited a certain verse (ayah), he prostrated to God. The verses are:
 * ۩ Q7:206, al Aʿrāf
 * ۩ Q13:15, ar-Raʻd
 * ۩ Q16:49, an-Nahl
 * ۩ Q17:107, al-Isra
 * ۩ Q19:58, Maryam
 * ۩ Q22:18, al-Hajj
 * ۩ Q22:77, al-Hajj
 * ۩ Q25:60, al-Furqan
 * ۩ Q27:25, an-Naml
 * ۩ Q32:15, as-Sajda
 * ۩ Q38:24, Ṣād
 * ۩ Q41:37, Fussilat
 * ۩ Q53:62, an-Najm
 * ۩ Q84:21, al-Inshiqaq
 * ۩ Q96:19, al-Alaq

In most copies of the Qur'an these are indicated by the symbol ۩, with an over-line on the word/s that invoked the prostration. Muslims must prostrate once in order to follow the Sunnah (example) of Muhammad and recite any one or more of the following along with Takbeer before and after the sujud,

Sajdah of forgetfulness
Sujud Sahwi or Sajdah of forgetfulness occurs during the ritual salat prayer. Out of forgetfulness a person can either omit obligatory parts of salat (Qabli) or add to the salat (Ba'adi). In either cases the person corrects their salat by doing the Sujud Sahwi.

Rule of direction of the prostration
Sujud is made only to God. In prayer, Muslims face the Kaaba in Mecca, Saudi Arabia.
