Quran 2:277 — The Heifer (Al-Baqarah)

Those who believe and lead a righteous life, and observe the Contact Prayers (Salat), and give the obligatory charity (Zakat), they receive their recompense from their Lord; they will have nothing to fear, nor will they grieve.

[2:276] GOD condemns usury, and blesses charities. GOD dislikes every disbeliever, guilty.

[2:278] O you who believe, you shall observe GOD and refrain from all kinds of usury, if you are believers.
