Asr prayer

[1] As with Zuhr prayer, if it is performed in congregation, the imam is silent except when announcing the takbir,[2] i'tidal,[3] and taslim.

[4] The period of Asr prayer begins approximately when the sun is halfway down from noon to sunset (various schools of thought of Islam differ on the starting point; some say that it begins when the shadow of an object equals its actual length plus its shadow during noon, others say that the actual length must be doubled).

Muslims are commanded to protect the middle prayer, meaning that it should be performed at all costs.

Letter 52 of Nahj al-Balagha contains instruction of Ali to his governors on the timings of salat, "The Asr prayers can be performed till the sun is still bright and enough time of the day is left for a person to cover a distance of six miles."

"[10] In another hadith: Muhammad said 'He who misses his Asr Salat (i.e. performs it after its specified time) is as if he had lost his wife, children and all his wealth.’ (Sahih Muslim)
