Al-Baqarah - 2:278

يَا أَيُّهَا الَّذِينَ آمَنُواْ اتَّقُواْ اللّهَ وَذَرُواْ مَا بَقِيَ مِنَ الرِّبَا إِن كُنتُم مُّؤْمِنِينَ
[2:278]
O you who believe! Be careful of (your duty to) Allah and relinquish what remains (due) from usury, if you are believers.
O ye who believe! Fear Allah, and give up what remains of your demand for usury, if ye are indeed believers.
O ye who believe! Observe your duty to Allah, and give up what remaineth (due to you) from usury, if ye are (in truth) believers.
