We slaughtered a sheep for the Messenger of Allah ﷺ, and he instructed us to prepare something from its stomach for him. He ate from it, then stood up and prayed without performing ablution.
حدثنا أحمد بن الحجاج أنبأنا حاتم بن إسماعيل عن محمد بن عجلان عن عباد بن عبيد الله بن أبي رافع عن أبي غطفان
ذبحنا لرسول الله ﷺ شاة فأمرنا فعالجنا له شيئا من بطنها فأكل ثم قام فصلى ولم يتوضأ
Its isnad is sahih. Abbad bin Ubaydullah bin Abu Rafi is Abdullah, and Abbad is his nickname. He is trustworthy, and his hadith appears in Muslim. Likewise Abu Ghatfan Marri. This hadith has been mentioned before from a group of the companions. See 14196.
