The Prohibition of Anger
Abu Hurayrah (radi Allahu anhu) said: A man said to the Prophet (sal Allahu alaihi wa sallam), “Advise me.” He (sal Allahu alaihi wa sallam) said, “Do not become angry.” The man repeated his request several times and He (sal Allahu alaihi wa sallam) said, “Do not become angry.”
An admonishment is an exhortation to a person concerning an important matter. This man requested from the Prophet (sal Allahu alaihi wa sallam) that he advise him. The Prophet (sal Allahu alaihi wa sallam) abstained from advising him with Taqwa (fear of Allah) as Allah, The Mighty, The Majestic, advised this Ummah with, as well as the People of the Book that came before us, until his statement, “Do not became angry.” He did this because he knew the state of this man, and Allah knows best. He knew that he frequently became angry, hence he advised him with his statement, “Do not become angry.”
The intent behind the prohibition of anger is not the natural anger that is from the natural inclination of man, but rather the intent is: Control yourself when you become angry so that you do not agitate and excite that anger. Anger is a live coal that the Shaytaan places in the heart of the son of Adam. Due to this, you find his eyes becoming red and his jugular veins swelling. His rationale and sanity may even depart due to his anger. Things will occur that its consequences are not praiseworthy. He may even dearly regret what has occurred. Because of this, the Prophet (sal Allahu alaihi wa sallam) advised him with this admonition. It is an admonishment to him and to whoever’s’ state is similar to his.
And from the Benefits of this hadith:
It is appropriate for the one giving a religious verdict and the teacher that he considers the condition of the person he is giving a verdict to, and the student he is speaking to in accordance with what their situation necessitates. If he were to speak to another person, then he would speak to him in another fashion.
And Allah Knows Best!
