I think it is justifiable to put your feelings about a situation over, but in a polite, calm and controlled manner. I don't like to see people displaying anger and I expect that they often, later, regret their outbursts.
Anger is a very dangerous emotion, therefore it needs to be controlled from health view point. I control myself by immediate isolation from situation that makes me angry.
The Messenger of Allah (peace and blessings of Allah be upon him) said: "If any of you becomes angry and he is standing, let him sit down, so his anger will go away; if it does not go away, let him lie down."
Keep Silent: If someone says something offensive to you, don't retaliate and say something mean back. If you're having an argument, be the better person, realize that nothing good comes out of petty arguments, and keep silent. When one is angry, they often lose self-control, and may utter words they later regret.
Life is like a boomerang. We are the source of what is happening to us. For example; if somebody talk to us in the way to make us angry. That means for sure; we did something bad in a near past and God send that person to punish us. So, we need to blame ourselves only. Then try to solve the problem in a calm way.
There is various methods are available for anger management. They are motivating to control the anger by counting 10-1, take physical exercise, taking glass of water and many more. But practically whenever the anger come the person have not time to use these activities. As per my opinion, one person should think over it and realize the consequences and dignity of your position will helpful to get rid of it.
