It was narrated that Jabir said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘Pre-emption is to be given in everything that is shared, whether it is a house or a garden. It is not right to sell it before informing one’s partner, and if he sells it he (the partner) has more right to it, unless he gives permission to sell it to someone else.” (Sahih)
