Quran 3:130 — The Amramites (Ali-'Imran)
O you who believe, you shall not take usury, compounded over and over. Observe GOD, that you may succeed.
[3:129] To GOD belongs everything in the heavens and the earth. He forgives whomever He wills, and punishes whomever He wills. GOD is Forgiver, Most Merciful.
[3:131] Beware of the hellfire that awaits the disbelievers.
