Narrated Ja`far bin `Amr bin Umaiya:
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.
My father said, "I saw Allah's Messenger (ﷺ) 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.''
