Is it permissible to purchase gold in installments while the item remains with the seller until the full price is paid?

It is not permissible to sell gold for cash with a delay in receiving the gold or postponing part of the price. This is because banknotes take the ruling of silver, and the Prophet, peace and blessings be upon him, forbade selling gold for silver except hand to hand and like for like.

To validate the contract, the buyer must bring the full amount, and the exchange must take place in the contract session. If the amount is not complete, no sale or purchase occurs, and the gold remains the property of the seller. If the buyer brings the full amount, a new contract is concluded.
