Lady Aisha (may Allah be pleased with her) narrates this saying of the Prophet Muhammad (peace be upon him): Indeed, the world is lush and sweet. If we give something from it with our own pleasure and without the greed of the receiver, and there is no evil of the soul in it, then there will be blessing in that thing for the person. But if we give it without our own pleasure and the receiver's greed is also involved, then there will be no blessing in it for him.
