Sayyiduna Jabir bin Abdullah (may Allah be pleased with both of them) narrates that the Messenger of Allah (peace and blessings be upon him) established the right of pre-emption (shuf‘ah) in every joint property that has not been divided, whether it is a house or a garden. It is not permissible for the owner to sell it without informing his partner. If the partner wishes, he may buy it; if he wishes, he may leave it. If the owner sells it without informing the partner, then the partner has more right to it.
