Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "If a person has a partner in a piece of land or a date-palm orchard, he does not have the right to sell his share until he informs his partner. If the partner is pleased, he may acquire it, and if he does not wish to, he may leave it."
