The ruling on selling at two prices: cash and deferred

Question:
Or if he says, "I will sell you this merchandise for one hundred riyals cash, or one hundred and twenty deferred," what is the ruling? And does he have to commit to one or not?

Answer:
This is not riba (usury or interest) if he says to you, "Buy this item for one hundred riyals cash, or one hundred and ten deferred." There is no harm in this, but on the condition that he decides on one of the two sales before parting ways. Either he takes it for one hundred cash, or one hundred and ten deferred. That is, they do not part ways until he has resolved on one of the two values. The increase due to the deferral is permissible, because there is no doubt that a deferred sale is not like a cash sale; there is an increase, no doubt about it. Those who say—meaning some modern writers or some who have not studied fiqh (Islamic jurisprudence)—that a deferred sale is not permissible and the increase is riba, this statement is not correct. This statement is not correct. Rather, it is permissible to sell on deferral with an increase over the cash price.
The Prophet (peace and blessings be upon him) And if there were no increase, people would not sell on deferral. This aspect, which is needed, would be obstructed. It is needed that one buys on deferral when he does not have the price at the present time, and buys on deferral even if there is an increase on him, for his benefit and to fulfill his need. If we were to block this door, the interests of people would be obstructed.
So this is not permissible. This statement is not correct, that a deferred sale is not permissible. And those who said it do not have knowledge or evidence in this issue. Yes.
The majority of scholars from the Salaf (the earliest generations) and the Khalaf (the later generations) are of the opinion that it is permissible, and the evidence indicates its permissibility. But the excessive increase, the excessive increase is not recommended, because it harms the one in need. Or he increases it by a suitable amount, a suitable increase that is not an excessive increase. Yes.
