When the Imam is called for As-Salat (the prayer) while he has in his hands something to eat.

Narrated Ja'far bin 'Amr bin Umaiya:

My father said, "I saw Allah's Apostle 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 ablutilon.''

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 ﷺ يَأْكُلُ ذِرَاعًا يَحْتَزُّ مِنْهَا، فَدُعِيَ إِلَى الصَّلاَةِ فَقَامَ فَطَرَحَ السِّكِّينَ، فَصَلَّى وَلَمْ يَتَوَضَّأْ.
