Abdullah b. Mas'ud reported Allah's Messenger (ﷺ) as saying
Whom do you count as" Raqub" amongst you? They (his Companions) said: One who has no children (the children are born unto him but they do not survive). Thereupon he (the Holy Prophet) said: He is not a Raqub but Raqub is one who does not find his child as the forerunner (in Paradise). He then said: Whom do you count as a wrestler amongst you? We said: He who wrestles with persons. He said: No, it is not he but one who controls himself when in a fit of rage.
This hadith has been narrated on the authority of A'mash with the same chain of transmitters.
Abu Huraira reported Allah's Messenger (ﷺ) as saying
The strong-man is not one who wrestles well but the strong man is one who controls himself when he is in a fit of rage.
Abu Huraira reported
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.
This hadith has been reported on the authority of Abu Huraira through another chain of transmitters.
Sulaiman b. Surad reported that two persons abused each other in the presence of Allah's Apostle (ﷺ) and the eyes of one of them became red as embers and the veins of his neck were swollen. Thereupon Allah's Messenger (ﷺ) said
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.
Sulaiman b. Surad reported that two persons abused each other in the presence of Allah's Apostle (ﷺ) and one of them fell into a rage and his face became red. Allah's Apostle (ﷺ) saw him and said
I know of a wording; if he were to utter that, he would get out (of the fit of anger) (and the wording is): I seek refuge with Allah from Satan, the accursed. Thereupon, a person went to him who had heard that from Allah's Apostle (ﷺ) and said to him: Do you know what Allah's Messenger (ﷺ) said? He (the Holy Prophet) said: I know of a wording; if he were to say that, (the fit) would be no more (and the words are): I seek refuge with Allah from Satan, the accursed. And the person said to him: Do you find me mad?
