Self-Control when angry
The Prophet (sal Allahu alaihi wa sallam) said, “The strong man is not the one who wrestles, but the strong man is in fact the one who controls himself in a fit of rage.”
[Sahih Al-Bukhari and Muslim]
Allah says (interpretation of the meaning): “(Those) who repress anger, and who pardon men; verily, Allah loves Al-Muhsinin (the good-doers).” (3:134)
People are usually impressed by the physical power and strength of somebody. But the real strength of a man lies in the fact that he should be able to wrestle with his passions in a fit of anger and avoid committing an act for which he may subsequently regret. This is a common observation that wild anger leads to many wrongdoing of which man repents later on or sheds tears over the ruin resulting from it.
And Allah knows best!
