English translation
188. Al-Mughirah bin Shu'bah said: "One night I was a guest of the Prophet ﷺ. He ordered the side of a goat (to be cooked for me), so it was roasted. He then took a knife, and started cutting bits (of the meat) from it for me. Bilāl came, and informed him of the prayer (that its time had come). So he put the knife aside, and remarked: 'What is the matter with him, may his hands be dusted!' Then he stood up to pray." Al-Anbārī (one of the narrators) added: "My moustache was very long, so he trimmed it upon a Siwāk,” or he said: “He told me that he would trim it upon a Siwāk.” (Sahīh)
