3- مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ مَنْصُورٍ عَنْ هِشَامِ بْنِ سَالِمٍ عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ
سَأَلْتُهُ عَنِ الرَّجُلِ يَأْكُلُ الرِّبَا وَهُوَ يَرَى أَنَّهُ لَهُ حَرَامٌ قَالَ لا يَضُرُّهُ حَتَّى يُصِيبَهُ مُتَعَمِّداً فَإِذَا أَصَابَهُ مُتَعَمِّداً فَهُوَ بِالْمَنْزِلَةِ الَّتِي قَالَ اللهُ عَزَّ وَجَلَّ.
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Muhammad ibn ‘Isa from Mansur from Hisham ibn Salim who has said the following:
“This is concerning my question before abu ‘Abd Allah 
, about the case of a man who consumes Riba ’ and he considers it lawful. He (the Imam) replied, ‘It does not harm him as long as he does not consume it knowing that it is unlawful, in which case he will face the condition of one who is mentioned in the words of Allah, most Majestic, most Glorious.
