It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings of Allah be upon him) said: "There is no validity in giving land to someone until his death or for his lifetime; whoever is given such land, it will belong to him during his life and after his death as well."
