Hadith 513
Sayyiduna Jabir (may Allah be pleased with him) reports: The Noble Prophet (peace and blessings be upon him) said: "Pre-emption (shuf‘ah) applies to every jointly owned house or garden. It is not permissible for the owner to sell the house or garden without the permission of the partner. If the partner wishes, he may take it, and if he wishes, he may leave it."
