Sunan Ibn Majah, Book 5, Hadith 1214 (In-Book)

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 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.”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ، عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ، عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ، قَالَ أَرْسَلَ مُعَاوِيَةُ إِلَى أُمِّ سَلَمَةَ فَانْطَلَقْتُ مَعَ الرَّسُولِ فَسَأَلَ أُمَّ سَلَمَةَ فَقَالَتْ إِنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ بَيْنَمَا هُوَ يَتَوَضَّأُ فِي بَيْتِي لِلظُّهْرِ وَكَانَ قَدْ بَعَثَ سَاعِيًا وَكَثُرَ عِنْدَهُ الْمُهَاجِرُونَ وَكَانَ قَدْ أَهَمَّهُ شَأْنُهُمْ إِذْ ضُرِبَ الْبَابُ فَخَرَجَ إِلَيْهِ فَصَلَّى الظُّهْرَ ثُمَّ جَلَسَ يَقْسِمُ مَا جَاءَ بِهِ ‏.‏ قَالَتْ فَلَمْ يَزَلْ كَذَلِكَ حَتَّى الْعَصْرِ ‏.‏ ثُمَّ دَخَلَ مَنْزِلِي فَصَلَّى رَكْعَتَيْنِ ثُمَّ قَالَ ‏ "‏ أَشْغَلَنِي أَمْرُ السَّاعِي أَنْ أُصَلِّيَهُمَا بَعْدَ الظُّهْرِ فَصَلَّيْتُهُمَا بَعْدَ الْعَصْرِ ‏" ‏ ‏.‏
