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.
Al-GhazaliDo 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.
Al-GhazaliNever have I dealt with anything more difficult than my own soul, which sometimes helps me and sometimes opposes me.
Al-GhazaliIn the intricate paths of life when difficulties and hardships confront a man, and the darkness of difficulty and suffering becomes long, it is patience only that acts like a light for a Muslim, that keeps him safe from wandering here and there, and saves him from the muddy marsh of disappointment, desperation and frustration.
