It is narrated from Sayyiduna Muawiyah (may Allah be pleased with him) that I heard the Prophet (peace and blessings be upon him) say: I am only a treasurer; the real giver is Allah. Therefore, if I give something to a person with a happy heart, it will be made blessed for him. But if I give something to someone to protect myself from his evil, or because of his insistence in asking, then it is like the one who keeps eating but is never satisfied.
