What did the Prophet Muhammad (saw) say about reciting Umm al-Qur'an in order to be credited with having observed prayer?
 Mahmud b. al-Rabi', on whose face the Messenger of Allah (may peace be upon him) squirted water from the well, reported on the authority of 'Ubada b. as- Samit that the Messenger of Allah (may peace be upon him) said:                      He who does not recite Umm al-Qur'an is not credited with having observed prayer.
