Did Sheikh Al-Qaradawi permit buying a house in Morocco through usurious banks due to the absence of Islamic banks, the high cost of real estate, and the rising price of rent?

It is impermissible to engage in Riba (usury/interest) for purchasing a home or anything else, except in cases of dire necessity that would lead to death or near-death. Living in a rented accommodation does not constitute a dire necessity.

There are Sharia (definition)-compliant alternatives to Riba in financial transactions, such as Tawarruq (monetization), Istisna' (manufacturing contract), and Murabaha (cost-plus financing). These alternatives fulfill the objectives of both parties in providing housing and achieving lawful profit.
