Chapter: Settlement (ṣulḥ)
A settlement is valid when concluded by anyone whose voluntary gifts are legally effective, whether the claim is acknowledged or denied. Thus, if the defendant admits owing the claimant a debt or a specific item and then settles for part of that debt or part of the claimed item, the transaction is a gift; it is only valid with the wording of a gift, not with the wording of settlement. If, on the other hand, he settles for a property other than the one claimed, the arrangement is a sale, valid even when expressed with the wording of settlement, and all the rulings of sale apply. Accordingly, when he settles a debt with a tangible item that shares with the debt the legal cause of ribā1, the consideration must be exchanged on the spot; but if the settlement is for something still owed in liability, it is void if they separate before delivery.
A settlement over a defect in the merchandise is valid; yet if the defect quickly disappears or is found never to have existed, the buyer may recover what he paid. Settlement is likewise permissible concerning a debt or an item whose exact amount cannot be determined. If one says, “Acknowledge the debt you owe me and I will give you such-and-such of it,” and the other acknowledges, the debt becomes binding on him, but he is not entitled to that promised portion.2
Section
If the defendant denies the claimant’s allegation, or remains silent because he is unaware of it,3 and they then effect a settlement, the settlement is valid: for him it is an absolution, while for the claimant it is a sale.
