What were the five prayers that the Angel Gabriel (peace be upon him) prayed with the Prophet Muhammad (saw)?
 Narrated Ibn Shihab:                     Once `Umar bin `Abdul `Aziz delayed the `Asr prayer a little. `Urwa said to him, "Gabriel descended and led the prayer in front of the Prophet " On that `Umar said, "O `Urwa! Be sure of what you say." "Urwa, "I heard Bashir bin Abi Masud narrating from Ibn Masud who heard Allah's Apostle saying, 'Gabriel descended and led me in prayer; and then prayed with him again, and then prayed with him again, and then prayed with him again, and then prayed with him again, counting with his fingers five prayers."
