`Uthman Ibn `Affan (rA) said:

I am surprised at a person who knows the world to be temporary yet loves it, the person who knows death to be certain yet does not take it seriously, and a person who believes in the hell fire and yet he commits sin, and a person who believes in the existence of Allah and yet he seeks assistance from others besides Allah, and a person who is aware of paradise and yet he is engaged in the worldly pleasures, and a person who knows shaytan is his enemy and yet he obeys what he dictates, and a person who believes in predestination and the divine decree of Allah yet feels aggrieved when something happens to him.
