Sahih Muslim Book 45, Hadith 142
This hadith has been reported on the authority of Abu Huraira through another chain of transmitters.
I heard Allah's Messenger (ﷺ) as saying: One is not strong because of one's wrestling skillfully. They said: Allah's Messenger, then who is strong? He said: He who controls his anger when he is in a fit of rage.
I know of a wording, if he were to utter that, his fit of rage (would be no more and that wording is): I seek refuge with Allah from Satan the accursed. The person said: Do you find any madness in me? Ibn al-'Ala' said: Do you see it? And he made no mention of the person.
