Is it necessary to review the company's origin and its relationship with banks for someone who contracts with it to build a house with monthly payments?

If the contract between the individual and the company adheres to Sharia principles, whether it is an ijarah (leasing) contract for building a house (where the materials are from the individual and the work from the company) or an istisna' (manufacturing) contract (where both materials and work are from the company), and the company is not known for engaging in prohibited activities, then there is no objection to dealing with it. There is no obligation to investigate its assets or its relationships with banks.
