The validity of installment sales when the seven conditions of sale are met

Question:
May Allah reward you. This questioner asks: What are the conditions for a valid installment sale?

Answer:
The seven conditions of sale. If the seven conditions of sale are met, the sale is valid, whether it is a lump sum or an installment sale, meaning whether the price is paid immediately or deferred, either in full or in installments. It is all the same; there is no harm. Allah has made selling lawful, and the default in transactions is permissibility, except for what evidence indicates is forbidden.
