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 will be ready to fight the enemy you can see.

Remember your contemporaries who have passed away and were your age. Remember the honors and fame they earned, the high posts they held, and the beautiful bodies they possessed. Today all of them are turned to dust. They have left orphans and widows behind them, their wealth is being wasted, and their houses turned into ruins.

Do not fix hopes on your health, and do not laugh away life. Remember how they walked and now all their joints lie separately, and the tongue with which they talked lightly is eaten away by the worms

Do not dispute with anyone in any matter as far as possible. For in argumentation lies much harm and its evil is greater than its benefit.
