Sunan Abi Dawud
Sunan Abi Dawud 2803
I came to Utbah ibn Abd al-Sulami and said: O Abu al-Walid, I went out seeking sacrificial animals, but I did not find anything that pleased me except a tharma' (an animal whose front teeth have fallen out), and I disliked it. What do you say? He said: Why did you not bring it to me? I said: Glory be to Allah! It is lawful for you and not lawful for me? He said: Yes, you have doubts while I do not have doubts. The Messenger of Allah (ﷺ) forbade the musfirah, the musta'sulah, the baqqa'ah, the mushayyi'ah, and the kasra'ah. As for the musfirah, it is the one whose ear is cut off until its ear canal is exposed; the musta'sulah is the one whose horn is uprooted from its base; the baqqa'ah is the one whose eye is punctured; the mushayyi'ah is the one that cannot follow the flock due to emaciation and weakness; and the kasra'ah is the broken-legged one.
