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) said: There is pre-emption (shuf‘a) in every jointly owned thing, whether it is a house or a garden. It is not permissible for one partner to sell such a thing until he informs his partner about it. If he sells it without informing his partner, then the partner has more right to it, until he is informed.
