Silsilah as-Sahihah 1150 — When is there blessing in Prophet’s gift?

It is narrated from Sayyiduna Muawiyah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I am a treasurer (that is, a keeper of the treasury), and the Giver is Allah Almighty. Whoever I give to with a cheerful heart (and willingness), there will be blessing in it for him. And whoever I give to because of his greed and persistent asking, then he will be like the person who keeps eating but is never satisfied."
