Rasulullah S.A.W. said:
"The greatest JIHAD is to battle your own soul, to fight the evil within yourself"
"Declare your jihad on thirteen enemies you cannot see - Egoism, Arrogance, Conceit, Selfishness, Greed, Lust, Intolerance, Anger, Lying, Cheating, Gossiping and Slandering. If you can master and destroy them, then you will be ready to fight the enemy you can see."
