It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Keep your wealth with yourself, do not give it to anyone, and whoever gives something to someone for a lifetime, then it becomes his, whether he is alive or dead, or he dies or it reaches his children.
