And if he recognises anything from it as isolated that it is interest...

[21] أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ الْوَشَّاءِ عَنْ أَبِي الْمَغْرَاءِ عَنِ الْحَلَبِيِّ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) كُلُّ رِبًا أَكَلَهُ النَّاسُ بِجَهَالَةٍ ثُمَّ تَابُوا فَإِنَّهُ يُقْبَلُ مِنْهُمْ إِذَا عُرِفَ مِنْهُمُ التَّوْبَةُ Ahmad Bin Muhammad, from Al Washa, from Abu Al Magra, from Al Halby who said, ‘Abu Abdullah – asws said: ‘Every interest which the people consume due to ignorance, then repent, so it would be Accepted from them, then the repentance is recognised from them’.

وَ قَالَ لَوْ أَنَّ رَجُلًا وَرِثَ مِنْ أَبِيهِ مَالًا وَ قَدْ عَرَفَ أَنَّ فِي ذَلِكَ الْمَالِ رِبًا وَ لَكِنْ قَدِ اخْتَلَطَ فِي التِّجَارَةِ بِغَيْرِهِ حَلَالٍ كَانَ حَلَالًا طَيِّباً فَلْيَأْكُلْهُ وَ إِنْ عَرَفَ مِنْهُ شَيْئاً أَنَّهُ رِبًا فَلْيَأْخُذْ رَأْسَ مَالِهِ وَ لْيَرُدَّ الرِّبَا And he – asws said: ‘If a man were to inherit some wealth from his father and has recognised that interest is among that wealth, but it has been mixed up in the business with other than Permissible that which was Permissible and good, so let him eat it; and if he recognises anything from it that is interest, so let him take the capital of his wealth and let him return the interest.

وَ أَيُّمَا رَجُلٍ أَفَادَ مَالًا كَثِيراً قَدْ أَكْثَرَ فِيهِ مِنَ الرِّبَا فَجَهِلَ ذَلِكَ ثُمَّ عَرَفَهُ بَعْدُ فَأَرَادَ أَنْ يَنْزِعَهُ فِيمَا مَضَى فَلَهُ وَ يَدَعُهُ فِيمَا يَسْتَأْنِفُ . And whichever man benefits with a lot of wealth and most of it is from the interest, so he was ignorant of that, then he recognises it afterwards, so he intends that he removes it from it regarding what is past, so it is for him, and he should leave with regards to what he resumes’.

[22] Consuming Interest out of Ignorance: عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ وَ أَحْمَدَ بْنِ مُحَمَّدٍ جَمِيعاً عَنِ ابْنِ مَحْبُوبٍ عَنْ خَالِدِ بْنِ جَرِيرٍ عَنْ أَبِي الرَّبِيعِ الشَّامِيِّ قَالَ سَأَلْتُ أَبَا عَبْدِ اللَّهِ ( عليه السلام ) عَنْ رَجُلٍ أَرْبَى بِجَهَالَةٍ ثُمَّ أَرَادَ أَنْ يَتْرُكَهُ فَقَالَ أَمَّا مَا مَضَى فَلَهُ وَ لْيَتْرُكْهُ فِيمَا يَسْتَقْبِلُ A number of our companions, from Sahl Bin Ziyad, and Ahmad Bin Muhammad, altogether from Ibn Mahboub, from Khalid Bin Jareer, from Abu Al Rabie Al Shamy who said, ‘I asked Abu Abdullah – asws about a man who consumed interest out of ignorance, then he intended to leave it’.
