I saw the Messenger of Allah ﷺ take slices from goat's shoulder and then eat them. He was called for prayer and he got'up, leaving aside the knife, and offered prayer but did not perform ablution.
رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَحْتَزُّ مِنْ كَتِفِ شَاةٍ فَأَكَلَ مِنْهَا فَدُعِيَ إِلَى الصَّلاَةِ فَقَامَ وَطَرَحَ السِّكِّينَ وَصَلَّى وَلَمْ يَتَوَضَّأْ قَالَ ابْنُ شِهَابٍ وَحَدَّثَنِي عَلِيُّ بْنُ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ عَنْ أَبِيهِ عَنْ رَسُولِ اللَّهِ ﷺ بِذَلِكَ
I saw Messenger of Allah ﷺ cutting part of the shoulder of mutton with a knife. He ate of it and then was called for prayer whereupon he got up and put down the knife and offered the prayer without performing new ablution.
رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَحْتَزُّ مِنْ كَتِفِ شَاةٍ فَأَكَلَ مِنْهَا فَدُعِيَ إِلَى الصَّلاَةِ فَقَامَ فَطَرَحَ السِّكِّينَ فَصَلَّى وَلَمْ يَتَوَضَّأْ
I saw Messenger of Allah ﷺ cutting part of the shoulder of mutton with a knife. He ate of it and then was called for prayer whereupon he got up and put down the knife and offered the prayer without performing new ablution. (Using translation from Bukhārī 5422)
«رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَحْتَزُّ مِنْ كَتِفِ شَاةٍ فَيَأْكُلُ مِنْهَا فَدُعِيَ إِلَى الصَّلَاةِ فَقَامَ فَطَرَحَ السِّكِّينَ فَصَلَّى وَلَمْ يَتَوَضَّأْ»
