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) ruled: "Pre-emption (shuf'ah) applies in everything that has not been divided. When boundaries have been set and the paths have been redirected, the right of pre-emption no longer remains."
