Bakr bin 'Abdullah al-Mazni بكر بن عبد الله المزني · General Behavior (Kitab Al-Adab)

Two men reviled each other in the presence of the Prophet (ﷺ). Then the eyes of one of them became red and his jugular veins swelled. The Apostle of Allah (ﷺ) said: I know a phrase by repeating which the man could get rid of the angry feelings: I seek refuge in Allah from the accursed devil. The man said: Do you see insanity in me.
