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 himand said, 'O Mughira! What is this? Don't you know that once Gabriel came and offered the prayer(Fajr prayer) and Allah's Messenger (ﷺ) prayed too, then he prayed again (Zuhr prayer) and so did Allah'sApostle and again he prayed (`Asr prayers and Allah's Messenger (ﷺ) did the same; again he prayed(Maghrib-prayer) and so did Allah's Messenger (ﷺ) and again prayed (`Isha prayer) and so did Allah'sApostle 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 Messenger (ﷺ)at the stated times of the prayers?" `Urwa replied, "Bashir bin Abi Mas`ud narrated like this on theauthority of his father." `Urwa added, "Aisha told me that Allah's Messenger (ﷺ) used to pray `Asr prayerwhen the sunshine was still inside her residence (during the early time of `Asr).
