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.

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.

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.
