Sahih al-Bukhari 2257

Musaddad narrated to us: Abd al-Wahid narrated to us: Ma mar narrated to us, from al-Zuhri, from Abu Salama ibn Abd al-Rahman, from Jabir ibn Abdullah, may Allah be pleased with them both, who said: The Messenger of Allah ruled that the right of pre-emption applies to everything that has not been divided. Once boundaries have been set and routes laid out, there is no right of pre-emption.
