Is it permissible to take a loan from the Islamic Bank in Hebron to build a house, knowing that it deals with legitimate Islamic transactions?

It is permissible to seek financing from an Islamic bank if it adheres to the Sharia-compliant regulations in its financial transactions, provided that the transaction is free from prohibitions and that the contract is genuine, not a disguise for usury. We cannot pass judgment on the aforementioned bank due to a lack of knowledge regarding its internal system. However, it is possible to distinguish between genuine adherence to Sharia principles and a mere claim of Islamization through Sharia-compliant regulations. One can inquire about this from trustworthy scholars in that particular location.
