Times of the Prayers

Narrated Ibn Shihab: Once `Umar bin `Abdul `Aziz delayed the
prayer and `Urwa bin Az−Zubair went to him and said, "Once in
'Iraq, Al−Mughira bin Shu`ba delayed his prayers and Abi
Mas`ud Al−Ansari went to him and said, 'O Mughira! What is
this? Don't you know that once Gabriel came and offered the
prayer (Fajr prayer) and Allah's Apostle prayed too, then he
prayed again (Zuhr prayer) and so did Allah's Apostle and
again he prayed (`Asr prayers and Allah's Apostle did the
same; again he prayed (Maghrib−prayer) and so did Allah's
Apostle and again prayed (`Isha prayer) and so did Allah's
Apostle and (Gabriel) said, 'I was ordered to do so (to
demonstrate the prayers prescribed to you)?'" `Umar (bin
`Abdul `Aziz) said to `Urwa, "Be sure of what you Say. Did
Gabriel lead Allah's Apostle at the stated times of the
prayers?" `Urwa replied, "Bashir bin Abi Mas`ud narrated like
this on the authority of his father." `Urwa added, "Aisha told
me that Allah's Apostle used to pray `Asr prayer when the
sunshine was still inside her residence (during the early time
of `Asr). Bukhari 1.501:
