766. hadíth
رَوَى إِسْمَاعِيلُ بْنُ مُسْلِمٍ عَنِ اَلصَّادِقِ جَعْفَرِ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: "تَبْطُلُ اَلشَّهَادَةُ فِي اَلرِّبَا وَ اَلْجَنَفِ وَ إِذَا قَالَ اَلشُّهُودُ إِنَّا لاَ نَعْلَمُ خَلِّ سَبِيلَهُمْ وَ إِذَا عَلِمُوا عَزِّرْهُمْ".
It is narrated by Isma'il ibn Muslim from Imam Jafar ibn Muhammad Al-Sadiq (a.s) from his father Imam Muhammad ibn Ali Al-Baqir (a.s) that he said: "Testimonies are invalidated in cases of usury (riba) and bias (janaf). If the witnesses say, 'We do not know,' then release them. However, if they are found to have known, then they should be disciplined (ta'zir)."
