He sold me his car for thirty thousand, and for every month I delayed in bringing the amount, he added a thousand?

Question:
Honorable Shaykh, may Allah grant you success, a man wants to sell his car to another for thirty thousand riyals, and he says, "If you bring the amount after a month, I will add a thousand riyals for you, and for every month you delay, I will add a thousand riyals for you." What is the ruling on this sale?

Answer:
This is the riba (usury or interest) of the pre-Islamic age of ignorance (jahiliyyah). This is the riba of the pre-Islamic age of ignorance. The increase due to delaying the current debt, where it is delayed and increased, is the riba of the pre-Islamic age of ignorance, riba al-nasi'ah (usury of deferment). Yes.
