وَ سَأَلَ رَجُلٌ اَلصَّادِقَ عَلَيْهِ اَلسَّلاَمُ عَنْ قَوْلِ اَللَّهِ عَزَّ وَ جَلَّ: يَمْحَقُ اَللّٰهُ اَلرِّبٰا وَ يُرْبِي اَلصَّدَقٰاتِ وَ قَدْ أَرَى مَنْ يَأْكُلُ اَلرِّبَا يَرْبُو مَالُهُ فَقَالَ "فَأَيُّ مَحْقٍ أَمْحَقُ مِنْ دِرْهَمٍ رِبًا يَمْحَقُ اَلدِّينَ فَإِنْ تَابَ مِنْهُ ذَهَبَ مَالُهُ وَ اِفْتَقَرَ".
A man asked Imam Jafar ibn Muhammad Al-Sadiq (a.s) about the saying of Allah (swt), the Almighty and Majestic: "Allah (swt) destroys usury and gives increase for charities." (Surah Al-Baqarah 2:276). He asked: "Yet I see those who consume usury, and their wealth increases." Imam (a.s) replied: "Is there any destruction greater than a dirham of usury that destroys one's religion? If he repents from it, his wealth will vanish, and he will become poor."
