Whom do you consider a wrestler among you? The people replied: (the man) whom the men cannot defeat in wrestling. He said: No, it is he who controls himself when he is angry.
Sunan Abi Dawud Book 43, Hadith 7
← Previous Hadith He then mentioned a similar tradition described above. This version has: Allah will fill his heart with security and faith. He did not mention the words "Allah will call him". This version further adds: He who gives up wearing beautiful garments when he is able to do so (out of humility, as Bishr's version has) will be clothed by Allah with the robe of honour, and he who marries for Allah's sake will be crowned by Allah with the crown of Kingdom.

Sunan Abi Dawud Book 43, Hadith 6 Next Hadith → Two men reviled each other in the presence of the Prophet (ﷺ) and one of them became excessively angry so much so that I thought that his nose will break up on account of excess of anger. The Prophet (ﷺ) said: I know a phrase which, if he repeated, he could get rid of this angry feeling. They asked: What is it, Messenger of Allah? He replied: He should say: I seek refuge in Thee from the accursed devil. Mu'adh then began to ask him to do so, but he refused and persisted in quarrelling, and began to enhance his anger.
