Is purchasing a car in installments through bank financing for seventy percent of the installment, at a ten percent interest rate over four years, considered an installment sale, and is it permissible?

The scenario mentioned in the question describes an interest-bearing loan, and it is forbidden to borrow with it or to purchase a car through it from usurious banks. "The Messenger of Allah, may Allah bless him and grant him peace, cursed the one who consumes usury, the one who pays it, its scribe, and its two witnesses," and he said, "they are all equal," narrated by Muslim. As for installment sales, they are permissible with their Sharia-compliant conditions and away from usurious banks.
