May peace be upon you
A father was concerned about his son who has an anger management problem. The son got angry almost everyday. He will shout profanities to anyone in front of him.
One day, the father said to his son, "Son, every time you feel anger welled up, go to the barn. Take with you a hammer and some nails."
"Then drive in the nails using the hammer until you feel satisfied."
So...every time the son feels angry, he takes the hammer and drives in the nails on the walls of the barn.
After one month, the father said to the son, "This time..pull out all the nails..."
Even though he felt peculiar, he just followed his father's instruction.
"What can you see on the walls, son."
"The walls are full of holes and they look rather ugly."
"Son..what you see is the effect of anger. When you get angry at someone you will not only hurt them but yourself. They might forgive you but the hurt might not go away. The wounds you inflicted on them might heal, but the scars may stay forever. And you also hurt yourself by becoming a bitter and unhappy person."
Anger can consume a man just like fire.
May Allah bless us with patience and calmness.
