Ibn Shihab reported,

Umar bin Abdul-Aziz once delayed the prayer, so Urwa bin Zubayr came in to see him and informed him that Mughira bin Shuba had likewise delayed the prayer one day while he was in Kufa. Abu Masud al-Ansari came in to see him and said, "What is this, Mughira? Do you not know that Jibreel descended and prayed, and the Messenger of Allah ﷺ prayed with him, then he prayed and the Messenger of Allah ﷺ prayed with him, then he prayed and the Messenger of Allah ﷺ prayed with him, then he prayed and the Messenger of Allah ﷺ prayed with him, then he prayed and the Messenger of Allah ﷺ prayed with him, and then he said, 'With this I have been commanded'?"Umar said to Urwa, "Be careful what you narrate, Urwa. Was it really Jibreel عليه السلام who established the times of prayer for the Messenger of Allah ﷺ?"Urwa replied, "That is how Bashir bin Abu Masud used to narrate it from his father."

أخبرنا يحيى بن يحيى التميمي قال قرأت على مالك

عن ابن شهاب

أن عمر بن عبد العزيز أخر الصلاة يوما فدخل عليه عروة بن الزبير فأخبره أن المغيرة بن شعبة أخر الصلاة يوما وهو بالكوفة فدخل عليه أبو مسعود الأنصاري فقال ما هذا يا مغيرة أليس قد علمت أن جبريل نزل فصلى فصلى رسول الله ﷺ ثم صلى فصلى رسول الله ﷺ ثم صلى فصلى رسول الله ﷺ ثم صلى فصلى رسول الله ﷺ ثم صلى فصلى رسول الله ﷺ ثم قال بهذا أمرت فقال عمر لعروة انظر ما تحدث يا عروة أو إن جبريل عليه السلام هو أقام لرسول الله ﷺ وقت الصلاة فقال عروة كذلك كان بشير بن أبي مسعود يحدث عن أبيه
