The ruling on installment sales with the transfer of ownership of the goods delayed until full payment is made

Question:
This questioner asks, Shaykh, about the ruling on selling land on installments, with the transfer of ownership of the land delayed until the full price is paid?

Answer:
The completion of the sale, the completion of the contract by offer and acceptance, is necessary. It is also necessary to take possession by vacating, meaning that he sees the land, knows its boundaries, and knows its area. As for whether he buys it for a cash price, a deferred price, or an installment price, there is no harm. Allah has made selling lawful and has forbidden riba (usury or interest) in land and in other things. However, the seller pledging it as security for its price, the seller pledging it for its price, there is no harm in that. Yes.
