Yes, if I sold the house for one hundred dirhams payable in one year, then bought it back for two hundred kilograms of dates in cash, this is permissible and presents no problem, because both disparity in exchange and deferment are permissible between dirhams and dates. If disparity and deferment are explicitly permissible between them, then this case is permissible all the more so.

In summary, this issue has three forms:

The first: I sell you this house for one thousand dirhams payable in one year, then buy it back for eight hundred dirhams in cash. This form is impermissible, and it is the inah transaction.

The second: I sell you this house for ten dinars payable in one year—worth one hundred dirhams—then buy it back for eighty dirhams in cash. According to the author’s view, this is permissible, because the price for which I bought it back is not of the same kind as the price for which I sold it.

The third: I sell it to you for one hundred dirhams payable in one year, then buy it back for one hundred kilograms of dates in cash. In this case, it is permissible even according to the author’s view, because he said, “of a different kind.”

Thus, we now have the following:

If he buys it back with the same kind as the original price, it is unquestionably prohibited.

If he buys it back with something of a different kind, between which and the original price riba of deferment does not apply, it is unquestionably permissible.

If he buys it back with something of a different kind, but riba of deferment applies between it and the original price, then according to the author’s view it is permissible; but according to the stronger view, it is impermissible. For although riba of excess between the first and second prices may be permissible, riba of deferment is prohibited.
