You should desire for others what you desire for yourself, and hate for others what you hate for yourself. Do not oppress, just as you do not like to be oppressed. Do good to others just as you would like good to be done to you. Dislike in yourself what you dislike in others. Accept that treatment from others which you would like others to accept from you. Do not say to others what you do not like to be said to you.
Ali ibn Abi TalibGreed 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.
