Sayyiduna Jabir (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said to the Ansar: Do not give your wealth as 'Umra (life grant), because whatever is given to someone as 'Umra during his lifetime becomes his property, and after his death, it will go to his heirs.
