Imam Khomeiniin his famous work of "an exposition on Forty Hadith" explains the matter as following:
Consider this opportunity as valuable, until you are alive, your faculties and your powers are still under control, and you are young.
Think about a cure before it is too late, and before moral maladies overpower your existence, and evils take deep roots in your existence and take you in the grips of their tentacles.
Drive them away, find out a way of extinguishing the fire of your sensuality and passion.
The best remedy prescribed by mystics and moralists is to concentrate upon each one of the evil habits that you detect in yourself, and offer an effective resistance against them. Fight bravely against your carnal self.
Act unceasingly all the time against those vicious yearnings. Pray Almighty to assist you in this battle.
Undoubtedly after sometime hideous habits would leave you, and Satan and his legions would vacate the fortress, and the battalions of heavenly armies would be installed in their stead.
One of the moral maladies, which may destroy one, cause torment of the grave, and plague man in this world, is the maltreatment of the people of his household, his neighbors, his colleagues and others around him, Imam further explains, Imam further explains.
It is the product of passion and sensuality.
If the mujahid is determined on correcting himself, he can counter those impulses of indignation, resentment and vituperation with gentleness and kindness, remembering the Hereafter and the chastisements therein. He should curse the Devil in his heart and take refuge in God.
