Abu Talha saw Messenger of Allah ﷺ lying down upon his belly in the mosque. He came to Umm Sulaim and said: I saw Messenger of Allah ﷺ lying down upon the belly in the mosque, and I think he is hungry. The rest of the hadith is the same (but with the addition of these words) that Messenger of Allah ﷺ ate (the food) and so did Abu Talha, Umm Sulaim and Anas b. Malik, but there was left some. thing which we presented to our neighbours.  

رَأَى أَبُو طَلْحَةَ رَسُولَ اللَّهِ ﷺ مُضْطَجِعًا فِي الْمَسْجِدِ يَتَقَلَّبُ ظَهْرًا لِبَطْنٍ فَأَتَى أُمَّ سُلَيْمٍ فَقَالَ إِنِّي رَأَيْتُ رَسُولَ اللَّهِ ﷺ مُضْطَجِعًا فِي الْمَسْجِدِ يَتَقَلَّبُ ظَهْرًا لِبَطْنٍ وَأَظُنُّهُ جَائِعًا وَسَاقَ الْحَدِيثَ وَقَالَ فِيهِ ثُمَّ أَكَلَ رَسُولُ اللَّهِ ﷺ وَأَبُو طَلْحَةَ وَأُمُّ سُلَيْمٍ وَأَنَسُ بْنُ مَالِكٍ وَفَضَلَتْ فَضْلَةٌ فَأَهْدَيْنَاهُ لِجِيرَانِنَا
