Jabir (b. 'Abdullah) (Allah be pleased with him) reported Allah's Messenger (may peace be upon him) having said: Keep your property to yourselves and do not squander it, for he who conferred a life grant upon another that property will belong to him upon whom it is conferred whether he lives or dies, and (would pass on) to his successors (as heritage).
