Always consider your intellect to be lacking; otherwise too much faith in it surely leads to error.

No wealth like education and no poverty like ignorance

There is no capital more useful than intellect and wisdom, and there is no indigence more injurious than ignorance and unawareness.

The sin which makes you sad and repentant is more liked by Allah than the good deed which turns you arrogant.

Greed takes a person to the watering place but gets him back without letting him drink. It undertakes responsibility but does not fulfill it. Often the drinker gets choked before quenching his thirst. The greater the worth of a thing yearned for, the greater is the grief for its loss. Desires blind the eyes of understanding. The destined share would reach him who does not approach it.

A man is hid under his tongue.

To fight against one's desires is the greatest of all fights.
