Contemporary Applications
Would salam contracts apply to apartments and houses sold before construction is completed?
According to the majority of contemporary scholars, this is considered to be a manufacturing contract (‘aqd al-istiṣnâ‘). This transaction is considered a type of salam by (A) + (+M, +S), which means all of the conditions of salam will apply to it, including the immediate payment of the whole price (A) + (+S) or within three days (-M). There is an agreement of the four madh-habs, however, that salam is not acceptable in buildings, because their site must be specified, and if it is, then it is a particular (non-substitutable) item, and salam is not applicable to those.
However, (-H) considers it a separate contract, since, unlike salam, it involves the making of the commodity. This position allows the buyer to pay the price in installments. Yet, according to (H), this contract will turn into salam if a deadline is set for the submittal of the commodity. The two disciples of Abu Ḥaneefah held a different position, and allowed setting a deadline in the manufacturing (istiṣnâ‘) contract.
The Fiqh Assembly of the OIC (Organization of the Islamic Conference) indicated that a deadline should be set, and its appointment should not change the contract from istiṣnâ‘ to salam. The assembly approved the sale of homes before their construction and also paying the price in installments, as long as there is an accurate description of the property being sold. – Resolution # 65 (7/3), Sixth Annual Conference of the OIC, 1412 AH/ 1992 CE.
