Umar bin Abd al-Aziz delayed the prayer one day, so Urwah bin al-Zubayr came to him and told him that Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him) delayed the prayer one day while he was in Kufah, and Sayyiduna Abu Mas'ud al-Ansari (may Allah be pleased with him) went to him and said: O Mughirah, do you not know that Jibril (peace be upon him) came down and prayed, so the Messenger of Allah (peace and blessings be upon him) prayed, then he said: "This is what I have been commanded." Umar bin Abd al-Aziz said to Urwah: O Urwah, know what you are narrating! Was it Jibril who fixed the time of prayer for the Messenger of Allah (peace and blessings be upon him)? Urwah said: This is what Bashir bin Abi Mas'ud used to narrate from his father.
