witr obligatory. 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. Other types of sujud Sajdah of thankfulness This is from the sunnah of the Islamic prophet Muhammad that whenever he used to hear news which would make him happy, he would make sujud to thank God. 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. This act (sujud) is the sign and symbol of the great respect that Muslims attach to God/Allah because He is giver and that He is Merciful too he who ask for His mercy and Grace. 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.

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 sujud Sujud is made only to God. In prayer, Muslims face the Kaaba in Mecca, Saudi Arabia, but make their sujud to God, not the Kaaba. The Kaaba is only a united direction that Muslims face as it is the order of God in the Qur'an. If any person claiming to be Muslim makes a sujud to any thing/deity/person other than God, he is considered a disbeliever, unless it is forced upon them. Sayings during sujud There are numerous things that a Muslim can say during sujud as is evident from the example of Muhammad. Among them are duas (prayers for God's help), hamd (praising
