Sahih al-Bukhari, Hadith 208 ⓘ
Narrated Ja`far bin `Amr bin Umaiya: My father said, "I saw Allah's Messenger 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."
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.
