3830 - وَ رَوَى عَبْدُ اَلرَّحْمَنِ بْنُ اَلْحَجَّاجِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ : سَأَلْتُهُ عَنِ اَلرَّجُلِ يَشْتَرِي اَلْمَبِيعَ بِالدِّرْهَمِ وَ هُوَ يَنْقُصُ اَلْحَبَّةَ وَ نَحْوَ ذَلِكَ أَ يُعْطِيهِ اَلَّذِي يَشْتَرِي مِنْهُ وَ لاَ يُعْلِمُهُ أَنَّهُ يَنْقُصُ قَالَ "لاَ إِلاَّ أَنْ يَكُونَ مِثْلَ هَذِهِ اَلْوَضَاحِيَّةِ يَجُوزُ، كَمَا يَجُوزُ عِنْدَنَا عَدَداً".
Hadith.3830 - Abd al-Rahman ibn al-Hajjaj narrated from Abu Abdullah 
:
"I asked Imam about a man who purchases a commodity with a dirham, and the dirham is deficient by a fraction, such as a grain or the like. Should he give it to the seller without informing him that it is deficient?"
Imam said: 'No, unless it is something like these small coins (al-wadaḥiyyah), which are commonly accepted, just as we accept them by count.'"
