Hadith 406
Sayyiduna Ali (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings be upon him) said: "Allah Almighty has fixed in the wealth of the rich Muslims a portion for their poor that is sufficient for their poor, so that the poor do not fall into excessive hardship when they are hungry. Beware of the behavior that the rich show towards them! Allah Almighty will take a strict account from them on the Day of Resurrection, then He will punish them severely."
