Narrated Ja`far bin `Amr bin Umaiya:
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ ، قَالَ حَدَّثَنَا اللَّيْثُ ، عَنْ عُقَيْلٍ ، عَنِ ابْنِ شِهَابٍ ، قَالَ أَخْبَرَنِي جَعْفَرُ بْنُ عَمْرِو بْنِ أُمَيَّةَ ، أَنَّ أَبَاهُ ، أَخْبَرَهُ أَنَّهُ، رَأَى رَسُولَ اللَّهِ صلى الله عليه وسلم يَحْتَزُّ مِنْ كَتِفِ شَاةٍ، فَدُعِيَ إِلَى الصَّلاَةِ فَأَلْقَى السِّكِّينَ فَصَلَّى وَلَمْ يَتَوَضَّأْ.
My father said, "I saw Allah's Messenger (ﷺ) taking a piece of (cooked) mutton from the shoulder region and then he was called for prayer. He put his knife down and prayed without repeating ablution."
