Al-Baqarah 2:281

<h2>The Necessity of Taqwa and Avoiding Riba</h2><p>Allah commands His believing servants to fear Him and warns them against what would bring them closer to His anger and drive them away from His pleasure. Allah said,</p><p>يأَيُّهَا الَّذِينَ ءَامَنُواْ اتَّقُواْ اللَّهَ</p><p>(O you who believe! Have Taqwa of Allah) meaning, fear Him and remember that He is watching all that you do.</p><p>وَذَرُواْ مَا بَقِىَ مِنَ الرِّبَواْ</p><p>(And give up what remains of Riba) meaning, abandon the Riba that people still owe you upon hearing this warning,</p><p>إِن كُنتُم مُّؤْمِنِينَ</p><p>(if you indeed have been believers) believing in the trade that He allowed you and the prohibition of Riba. Zayd bin Aslam, Ibn Jurayj, Muqatil bin Hayyan and As-Suddi said that this Ayah was revealed about Bani `Amr bin `Umayr, a sub-tribe of Thaqif, and Bani Al-Mughirah, from the tribe of Bani Makhzum, between whom were outstanding transactions of Riba leftover from time of Jahiliyyah. When Islam came and both tribes became Muslims, Thaqif required Bani Al-Mughirah to pay the Riba of that transaction, but Bani Al-Mughirah said, "We do not pay Riba in Islam." `Attab bin Usayd, the Prophet's deputy on Makkah, wrote to the Messenger of Allah about this matter. This Ayah was then revealed …

And guard yourselves against a day in which ye will be brought back to Allah. Then every soul will be paid in full that which it hath earned, and they will not be wronged.

And fear the Day when ye shall be brought back to Allah. Then shall every soul be paid what it earned, and none shall be dealt with unjustly.

And be afraid of the Day when you shall be brought back to Allah. Then every person shall be paid what he earned, and they shall not be dealt with unjustly.

And guard yourselves against a Day when you will be returned to God; then each soul will be rewarded fully for what it has earned, and they will not be wronged.
