Salah ("Muslim prayer") 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.Prayer is obligatory for all Muslims except those who are prepubescent, are menstruating, or are experiencing bleeding in the 40 days after childbirth.Before conducting salah, a Muslim has to perform a ritual ablution. The minor ablution is performed using water (wudu), or sand (tayammum) when water is unavailable or not advisable to use for reasons such as illness. Wudu is performed by Muslims according to the instructions of God given in the Quran. "Adhan" is the Islamic call to prayer, recited by the one known as the muezzin for the five obligatory prayers. A second call immediately before praying, known as the Iqama, is for the assembled Muslims in the prayer area to line up for the beginning of the prayers.

Muslims are commanded to perform prayers five times a day.These times are measured according to the movement of the sun. These are: near dawn (fajr), after midday has passed and the sun starts to tilt downwards/noon (zuhr), in the afternoon (asr), just after sunset (maghrib) and around nightfall (Isha). Under some circumstances ritual worship can be shortened or combined (according to prescribed procedures).
