(33) باب مَا جَاءَ عَنِ النَّبِيِّ صلى الله عليه وسلم مِنَ الرُّخْصَةِ فِي قَطْعِ اللَّحْمِ بِالسِّكِّينِ
Narrated Ja'far bin 'Amr bin Umayyah Ad-Damri:
From his father who said that he saw the Prophet (ﷺ) making incisions (with a knife) into a piece of a lamb shoulder which he ate from, then he went to perform Salat without performing Wudu'.[Abu 'Eisa said:] This Hadith is Hasan Sahih and there is something on this topic from Al-Mughirah bin Shu'bah.
