He said, "Yahya ibn Yahya al-Laythi related to me from Malik ibn Anas from Ibn Shihab that one day Umar ibn Abdal-Aziz delayed the prayer. Urwa ibn az-Zubayr came and told him that al-Mughira ibn Shuba had delayed the prayer one day while he was in Kufa and Abu Masud al- Ansari had come to him and said, 'What's this, Mughira? Don't you know that the angel Jibril came down and prayed and the Messenger of Allah (ﷺ) prayed.' Then he prayed again, and the Messenger of Allah (ﷺ) prayed. Then he prayed again, and the Messenger of Allah (ﷺ) prayed. Then he prayed again, and the Messenger of Allah (ﷺ) prayed. Then he prayed again, and the Messenger of Allah (ﷺ) prayed. Then Jibril said, 'This is what you have been ordered to do.' Umar ibn Abd al-Aziz said, 'Be sure of what you relate, Urwa. Was it definitely Jibril who established the time of the prayer for the Messenger of Allah?' " Urwa said, "That's how it was related to Bashir ibn Abi Masud al-Ansari by his father."
