The love of the world is the root of all evil.
This world is a prison for the Faithful, but a Paradise for unbelievers.
The world is a magician greater than Harut and Marut, and you should avoid it.
The world is sweet in the heart, and green to the eye; and verily God hath brought you, after those that went before you: then look to your actions, and abstain from the world and its wickedness.
Be in the world like a traveller, or like a passer on, and reckon yourself as of the dead.
All goodness is to the rememberance of God and that which aids thereto.
