Hadith 6:230
Abu Dawud narrated to us, from al-Rabi’, who said: I heard Ibn Sirin say: "The anus of the deceased, his mouth, and his nostrils are to be stuffed with cotton." And Muhammad said: "Whatever you treat of his anus, treat it with your left hand."
حدثنا أبو داود عن الربيع قال سمعت بن سيرين يقول يحشى دبر الميت وفوه ومنخراه قطنا وقال محمد ما عالجت دبره فعالجه بيسار
