Narrated It was narrated that Muhammad bin ‘Ali said:
Some people came to `Ali (رضي الله عنه) and complained about `Uthman`s tax collector. My father said to me: take this letter to `Uthman (رضي الله عنه) and tell him: The people are complaining about your tax collector, and this is the instruction of the Messenger of Allah (ﷺ) about collecting zakah, tell them to follow it. So I went to `Uthman and told him about that, He (the narrator) said: If he had wanted to say anything about `Uthman, he would have said it on that occasion - i.e., saying something bad.
Narrated It was narrated that Abu `Ubaid, the freed slave of ‘Abdur-Rahman bin ‘Awf, said:
Then I was present with ‘Ali. He prayed before delivering the khutbah, with no adhan or iqamah, then he delivered the khutbah. He said: O people, the Messenger of Allah (ﷺ) forbade eating from your sacrificial animals after three days, so do not eat from them after today.
