“If the Messenger of Allah (ﷺ) missed the four Rak’ah before the Zuhr, he would perform them after the two Rak’ah which come after the Zuhr.”
Sunan Ibn Majah Book 5, Hadith 356
← Previous Hadith It was narrated from Abu Ayyub that the Prophet (ﷺ) used to perform four Rak’ah before the Zuhr when the sun had passed its zenith, and he did not separate them with a Taslim. He said, “The gates of heaven are opened when the sun passes its zenith.”

Sunan Ibn Majah Book 5, Hadith 355 Next Hadith → “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 (ﷺ) was performing ablution for the Zuhr in my house and he had sent a Sa’i,* the Muhajirun 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’i kept me from praying them after Zuhr, so I prayed them after ‘Asr.”
