Ash-Shama'il Al-Muhammadiyah — Hadith #47900

Mahmud ibn Ghaylan told us, saying: Waki’ told us, saying: Mis’ar told us, on the authority of Abu Sakhra Jami’ ibn Shaddad, on the authority of al-Mughirah ibn ‘Abd Allah, on the authority of al-Mughirah ibn Shu’bah, who said: I was a guest with the Messenger of Allah, may God bless him and grant him peace, one night, and a roasted side of lamb was brought to him. Then he took the knife and began to cut it, and he cut some of it for me with it. He said: Then Bilal came to inform him of the prayer, so he threw down the knife. He said: What is wrong with him, may his hands be covered in dust? He said: His mustache had grown long, so he said to him: I will cut it for you on a siwak or cut it on a siwak.
