is gold, the increase may not consist of gold; and if the capital is silver, no increase may consist of silver. Hold fast to this principle.

When the capital is in dirhams or dinars, an iqāla may not be concluded for only part of the salam goods; but if the salam capital was paid in merchandise, a partial rescission is permissible, because dinars and dirhams yield an immediate benefit and the transaction would otherwise fall, in their view, under the heading of a sale combined with a loan.

If someone sells a commodity for a deferred price and the seller then asks for the sale to be rescinded in return for an added amount, there is no harm in that provided the increase applies to the whole price, whether it is paid immediately or deferred—unless the increase is of the same kind as the commodity sold. In that case no delay is allowed; only cash payment is valid.

If, on the other hand, the buyer is the one who seeks the rescission, the commodity is still intact, and the term has fallen due, then the entire increase is permissible, whether paid in silver or in gold. The same holds for the original capital, whether in silver or gold, so long as the increase is taken on the spot and none of it is deferred.

Should the rescission occur before the due date, the increase is likewise permissible provided it is received immediately and nothing is delayed. Alternatively, if it takes place before maturity, an increase of any kind is also valid, whether paid in cash or on credit—except when it is of the same species as the commodity sold. In that case payment must be immediate; deferring it is unsound.
