Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that Sayyiduna Umar bin Khattab (may Allah be pleased with him) consulted the Prophet Muhammad (peace be upon him) regarding giving his property in "Thamgh" (i.e., land) as charity. The Prophet Muhammad (peace be upon him) said: Give it as charity, such that you distribute its produce and keep the land itself with you, which cannot be sold nor gifted.
