What was the command of the Prophet Muhammad (peace be upon him) about the number of rak'ahs for the noon prayer?
 'Abdullah (b. Mas'ud) reported:                      The Apostle of Allah (may peace be upon him) said five rak'ahs of the noon prayer and when he completed the prayer, It was said to him: Has there been (commanded) an addition In prayer? He said: What is it? They said: You have said five rak'ahs, so he performed two prostrations.
