If one transaction is made an express condition of another, the existing sale may become contingent on a future event and create uncertainty (غرر). A separate promise does not suspend the validity of the original joint purchase.
The promise prepares a later transaction but does not itself transfer ownership. The later sale must still be concluded at the proper stage after the required ownership and possession exist.
