The strong man
Abu Hurayrah (radi Allahu anhu) reported the Messenger of Allah (sal Allahu alaihi wa sallam) said, “The strong man is not one who is good at wrestling, but the strong man is one who controls himself in a fit of rage.”
[Sahih al-Bukhari and Muslim]
This Hadith instructs oneself to keep in control in order to overcome his rage.
And Allah Knows Best!
