What is the ruling on building housing through the Development Bank via a contemporary Istisna'a contract applied by the Development Bank for Qataris, and what are the conditions for the contract to be Sharia-compliant?

The permissibility of the Istisna' contract is a matter of scholarly disagreement, with some scholars allowing it under specific conditions. It is not possible to rule on the mentioned bank transaction without knowing its terms. However, generally speaking, if the dwelling is purchased according to the aforementioned conditions, such that it is described in a way that removes ambiguity and is free from শরী'আ-forbidden elements, then there is no objection to the contract according to those who permit Istisna'.
