Brief Explanation
Benefits: … A teacher, mentor, and preacher should be wise and discerning, and should converse with people after assessing their intellectual level and temperament. In a state of anger, ordinary people are unable to distinguish between right and wrong, and they utter such words that cause hatred to arise in hearts, and the speaker himself later feels regret. Therefore, the Prophet sallallahu alayhi wa sallam has advised remaining silent in such a state.
