Anger or wrath is an intense emotional response. Often it indicates when one's basic boundaries are violated. Some have a learned tendency to react to anger through retaliation. Anger may be utilized effectively by setting boundaries or escaping from dangerous situations. Sheila Videbeck describes anger as a normal emotion that involves a strong uncomfortable and emotional response to a perceived provocation. William DeFoore, an anger-management writer, described anger as a pressure cooker: we can only apply pressure against our anger for a certain amount of time until it explodes.
Anger may have physical correlates such as increased heart rate, blood pressure, and levels of adrenaline and noradrenaline. Some view anger as an emotion which triggers part of the fight or flight brain response. Anger becomes the predominant feeling behaviorally, cognitively, and physiologically when a person makes the conscious choice to take action to immediately stop the threatening behavior of another outside force. The English term originally comes from the term anger of Old Norse language. Anger can have many physical and mental consequences.
Although anger is a natural feeling it can have negative effects on those who allow it to control them, and adverse effects on those around them. Anger can destroy relationships, health, property, and livelihood. Uncontrolled anger is one of the tools of Satan and it can lead to many evils and tragedies. For this reason Islam has a great deal to say about the emotion of anger.
Because anger is often associated with ‘fight or flight responses’, it is often difficult to separate an action that is done in self-defence (or to protect properties or families) from one that is done out of uncontrolled rage. It is ok to feel anger but it is not acceptable when a person allows it to overtake him and drive him to act in an unacceptable way, sometimes even leading to murder and mayhem. The story of an event in the life of one of Prophet Muhammad’s companions, his son-in-law Ali, demonstrates the difference.
Ali ibn Abi Talib was once fighting in a war, when the leader of the non-Muslim army attacked him. During the confrontation, Ali managed to overcome him and was on the verge of killing him, when his opponent spat in Ali’s face. Ali immediately stepped back and left the man alone. The man said, “You could have killed me, why did you stop? Ali answered, “I have no personal animosity toward you. I was fighting you because of your disbelief in and rebellion against God. If I had killed you after you spat in my face, it would have been because of my personal anger and desire for revenge, which I do not wish to take.”
The Prophet once asked his Companions, “Whom among you do you consider a strong man?” They replied, “The one who can defeat so-and-so in a wrestling contest.” He said, “That is not so; a strong man is the one who can control himself when he is angry”.
