Anger is a completely normal, usually healthy, human emotion. But when it gets out of control and turns destructive, it can lead to problems - problems at work, in your personal relationships and in the overall quality of your life. And it can make you feel as though you are at the mercy of an unpredictable and powerful emotion.
The Qurān says: “..Should anyone aggress against you, assail him in the manner he assailed you.”1 One is unable to oppress the oppressor to a higher degree of oppression than he was oppressed himself. If one swears twice responding to one swear, he has crossed the limits.
The Prophet Muhammad (peace be upon him) said: "No one has swallowed anything more excellent in the sight of God...than the anger he restrains, seeking to please God most high." Al-Tirmidhi, Hadith 1324
In a state of anger there are many sins that commits , insulting and harming a fellow believer; polluting the tongue with speaking impermissible things, and many other sins. In addition, sometimes a person performs such a sin that he is not able to control himself, or due to his anger, performs something that he would never be able to compensate for during the course of his entire life!
Imam Ja’far b. Muhammad as-Sadiq (as): “Anger is the key to all evil.”
In a state of anger the person should leave that area where he is, in order to control his emotions, if he has become upset while inside his house, then he should step outside. It has even been stated that if a person is standing then he should sit down or if he is sitting down then he should stand up or even drink some water to change his mood and control himself!
