Sayyiduna Abu Mas'ud (may Allah be pleased with him) said to Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him), when he had delayed the Asr prayer until evening: Listen! By Allah, O Mughirah, you 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 prayed, so the Messenger of Allah (peace and blessings be upon him) prayed; then he (peace and blessings be upon him) said: "This is how I have been commanded."
