A man asked “Ali (رضي الله عنه) about (sacrificing) a cow. He said: (it may be sacrificed) on behalf of seven people. He said: (What about a cow with) a broken horn? He said. It doesn`t matter. He said: (What if it is) lame? He said: If it can reach the place of sacrifice, then slaughter it. The Messenger of Allah (ﷺ) commanded us to examine the eyes and ears.

We were walking with ‘Uthman (رضي الله عنه) and saw a man entering ihram for both .`Uthman (رضي الله عنه) said Who is this? They said: `Ali. He said: Do you not know that I have forbidden this? He said: Yes, but I will not give up the advice of the Messenger of Allah (ﷺ) for your opinion.
Narrated It was narrated from `Abeedah that ‘Ali (رضي الله عنه) said:
The Messenger of Allah (ﷺ) said: `There will emerge some people among whom is a man with a defective arm, or an incomplete arm, or a small arm.` If you could exercise restraint, I would have told you what Allah promised on the lips of Muhammad (ﷺ) to those who kill them. ‘Abeedah said to `Ali (رضي الله عنه) Did you hear that from the Messenger of Allah (ﷺ)? He said: Yes, by the Lord of the Ka`bah; yes, by the Lord of the Ka`bah, yes, by the Lord of the Ka`bah.
