Sahih al-Bukhari, Hadith 675 ⓘ
Narrated Ja`far bin `Amr bin Umaiya: My father said, "I saw Allah's Messenger eating a piece of meat from the shoulder of a sheep and he was called for the prayer. He stood up, put down the knife and prayed but did not perform ablution.''
حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا إِبْرَاهِيمُ، عَنْ صَالِحٍ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي جَعْفَرُ بْنُ عَمْرِو بْنِ أُمَيَّةَ، أَنَّ أَبَاهُ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَأْكُلُ ذِرَاعًا يَحْتَزُّ مِنْهَا، فَدُعِيَ إِلَى الصَّلاَةِ فَقَامَ فَطَرَحَ السِّكِّينَ، فَصَلَّى وَلَمْ يَتَوَضَّأْ.
