What is the difference between a sale with a deferred price and an increase in the price, and repaying a loan with an increase on the loan?

Question:
He says: Honorable Shaykh, may Allah grant you success, what is the difference between increasing the debt on the debtor, and a sale with a deferred price where the seller takes an increase for the delay?

Answer:
The difference is clear. This is a sale of goods for a deferred price, and there is no doubt that the deferred price is higher than the immediate price. The two parties would never sell to people on credit if it were not for the increase and the greed for that increase; if there were no increase, they would not sell on credit, and the interests of people would be hindered. The Prophet (peace and blessings be upon him) bought on credit and borrowed on credit, so there is no problem with selling on credit; it is permissible, and people have a dire necessity for it. It is an explicit sale with no issue, yes. There is a difference between this and that. This is money being increased with money; a small amount of money is inflated and becomes a large amount of money without any benefit to the one who owes it. Unlike a deferred sale, where the benefit is apparent: the buyer benefits from the goods, and the seller benefits from the increase that returns to him. Yes.
