Whoever is pleased with his good actions and displeased with his bad actions is happy
How happy you feel when you help a poor needy man in which ever way you can.
You feel happy when you pray to God at dawn.
Your sense happiness, when you act for a noble cause.
All are good deeds which bring happiness for you when not only you benefit from it but others also benefit because of your action.
People who do evil deeds, who feel pleased and happy by cheating people, or lying to them or stealing something, or doing something that is forbidden, ultimately loose his/her happiness. He does not judge himself for his irresponsibility or question why he has done such evil deeds.
Surely, there is no truthful happiness in the heart of such a man.
There is true happiness if one commits a mistake, and finds himself guilty in the case of committing an evil action. Consequently, he asks mentally for God’s forgiveness and then repents. He apologizes to the people whom he has wronged
