Salah ("Muslim prayer", or Gen: ṣalāt; pl. صلوات ṣalawāt), called in some languages by the Persian-derived term namāz (Persian: نَماز) is one of the Five Pillars in the faith of Islam and an obligatory religious duty for every Muslim. It is a physical, mental, and spiritual act of worship that is observed five times every day at prescribed times. In this ritual, the worshiper starts standing, bows, prostrates, and concludes while sitting on the ground. During each posture, the worshiper recites or reads certain verses, phrases and prayers. The word salah is commonly translated to prayer but this definition might be confusing. Muslims use the words "Dua" or "Supplication" when referring to the common definition of prayers which is "reverent petitions made to God."
Salat is preceded by ritual ablution. Salat consists of the repetition of a unit called a rakʿah (pl. rakaʿāt) consisting of prescribed actions and words. The number of obligatory (fard) rakaʿāt varies from two to four according to the time of day or other circumstances (such as Friday congregational worship, which has two rakats). Prayer is obligatory for all Muslims except those who are prepubescent, are menstruating, or are experiencing bleeding in the 40 days after childbirth. Every movement in the salat is accompanied by the takbir except the standing between the ruku and sujud, and the ending which has a derivation of the Muslim greeting As-salamu alaykum.
Salat (ṣalāt) is an Arabic word whose basic meaning is "bowing, homage, worship, prayer." In its English usage, the reference of the word is almost always confined to the Muslim formal, obligatory worship described in this article.
