The Ruling on Buying from the Grocery Store and Paying at the End of the Month

The questioner:
Honorable Shaykh, what is your opinion on what some people do, which is buying some necessities and items from the grocery store and not paying the price immediately, but rather there is an agreement with the store owner to pay at the end of the month, for example? Is this the intended riba al-nasi'ah (usury of deferment) or not?

The Shaykh:
It does not contradict [the ruling]. If he sells goods for dirhams and says to him, "Pay me when I take the goods," or "Pay me when I take the goods," it does not contradict [the ruling]. This is a deferred sale. This is a deferred sale. There is no harm in it if they agree on it.

The questioner:
Honorable Shaykh.

The Shaykh:
But if he says, "Give me dates now, give me dates and I will give you dates in exchange after a year," this is haram (forbidden). Or if he says, "Give me rice, I will give you rice after a month or after a year," this is haram (forbidden) because it is nasi'ah (deferment). But if they buy rice or dates for deferred dirhams, there is no objection.
