حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ: حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنِ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ
أَنَّهُ رَأَى رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، تَوَضَّأَ مِنْ أَكْلِ ثَوْرِ أَقِطٍ، ثُمَّ رَآهُ أَكَلَ مِنْ كَتِفِ شَاةٍ، ثُمَّ صَلَّى، وَلَمْ يَتَوَضَّأْ
Abu Hurayrah (may Allah be well pleased with him) said that he saw the Messenger of Allah (sallallahu alayhi wa sallam) perform the minor ritual ablution because of eating cottage cheese. Then he saw him eat from the flank of a sheep, and then perform the ritual prayer without performing the minor ritual ablution.
