Do not get Angry

Abu Hurairah (R) reports,  a man asked the Prophet (peace be upon him) to give him advice, and he (peace be upon him) said,

Do not get angry.

The man repeated that several times and he (peace be upon him) replied (every time),

Do not get angry. [Bukhari]

Anger can destroy friendships and marriages. May Allah keep us away from such dangers.
