The Necessity of Taqwa and Avoiding Riba

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,

يأَيُّهَا الَّذِينَ ءَامَنُواْ اتَّقُواْ اللَّهَ

The gist of the fourth verse (278): يَا أَيُّهَا الَّذِينَ آمَنُوا اتَّقُوا اللَّـهَ وَذَرُ‌وا مَا بَقِيَ مِنَ الرِّ‌بَا إِن كُنتُم مُّؤْمِنِينَ those who believe, fear Allah and give up what still remains of the riba if you are believers" is that, after the revelation that prohibited riba, the giving and taking of the amount of ربا riba that remained due against anyone was also prohibited.

Explaining this, it can be said that ربا riba was rampant all over Arabia before it was prohibited by revelation. When verses earlier than the present one brought forth its prohibition, Muslims - following their Qur'an-oriented habit - abandoned all their ربا riba-related dealings. But some people had claims of unpaid ربا riba amounts on some others. In that connection, it so happened that Banu Thaqif and Banu Makhzum, two Arab tribes, had mutual ربا riba dealings and people from Banu Thaqif had claims of unpaid ربا riba amounts against Banu Makhznm. When Banu Makhzum became Muslims they, after having made their commitment to Islam, thought it to be impermissible to pay back the amount of ربا riba due. On the other side were Banu Thaqif; their people started pressing their claim. Since these people had become Muslims, but did have a mutual peace agreement, the people of Banu Makhzum told them that they had now entered the fold of Islam and had no intention of spending their Islamic earnings in paying off ربا riba.
