"O believers! Do not consume interest, multiplying it many times over. And be mindful of Allah, so you may prosper."
"and for their charging Ribā (usury or interest) while they were
forbidden from it, and for their devouring of the properties of the
people by false means. We have prepared, for the disbelievers among
them, a painful punishment."

Insha'Allah, Allah will see how you're staying clear from such a major sin, He will aid you and grant you fortune. Keep making Dua.
