A person requested the Holy Prophet (Sallallahu alaihi wa sallam) to advise him:
The Holy Prophet (Sallallahu alaihi wa sallam) said:
Don’t be angry.
He again and again requested for advice and each time the Holy Prophet (Sallallahu alaihi wa sallam) said:
Don’t be angry.
(Sahih Bukhari, Hadith No. 6116)
