The Prophet (ﷺ) said: Allah has revealed to me that you must be humble, so that no one oppresses another and boasts over another.
Sunan Abi Dawud Book 43, Hadith 123
← Previous Hadith when two men abuse one another, what they say is laid to the charge of the one who began it, so long as the one who is wronged does not go over the score.

Sunan Abi Dawud Book 43, Hadith 122 Next Hadith → While the Messenger of Allah (ﷺ) was sitting with some of his companions, a man reviled AbuBakr and insulted him. But AbuBakr remained silent. He insulted him twice, but AbuBakr controlled himself. He insulted him thrice and AbuBakr took revenge on him. Then the Messenger of Allah (ﷺ) got up when AbuBakr took revenge.

AbuBakr said: Were you angry with me, Messenger of Allah?

The Messenger of Allah (ﷺ) replied: An angel came down from Heaven and he was rejecting what he had said to you. When you took revenge, a devil came down. I was not going to sit when the devil came down.

Sunan Abi Dawud Book 43, Hadith 124
