Is it permissible to resort to social housing with a usurious loan to meet a necessity, knowing that the questioner weeps fearing to wage war against Allah?

It is not permissible to enter into a contract that necessitates borrowing with riba (usury/interest), because borrowing with riba is one of the greatest major sins and is only permissible out of necessity. Marriage is not among the pressing necessities. "And whoever fears Allah – He will make for him a way out and will provide for him from where he does not expect."
