It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) "established the right of pre-emption in whatever has not yet been divided. When boundaries have been set and the paths have been redirected, the right of pre-emption no longer remains."
