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.
Ali ibn Abi TalibDo not share the knowledge with which you have been blessed with everyone in general, as you do with some people in particular; and know that there are some men in whom Allah, may He he glorified, has placed hidden secrets, which they are forbidden to reveal.
Ali ibn Abi TalibThy lot or portion of life is seeking after thee; therefore be at rest from seeking after it.
Ali ibn Abi Talib
