It was narrated that 'Abdullah bin Harith said: "Mu'awiyah sent word to Umm Salamah, and I went with his envoy who put the question to Umm Salamah. She said: 'While the Messenger of Allah P.B.U.H was performing ablution for the Zuhr in my house and he had sent a Sa'i the Muhajirin gathered around him in large numbers, and he was busy dealing with them. When a knock on the door came, he went out and performed the Zuhr, then he sat and distributed what had been brought to him.' She said: 'He continued doing that until the 'Asr. Then he came into my house and performed two Rak'ah. Then he said: "The matter of the sa'; kept me from praying them after Zuhr, so I prayed them after 'Asr." (Da'if)
