Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 11
وَ رُوِيَ عَنِ اِبْنِ مُسْكَانَ عَنْ إِسْحَاقَ اَلْمَدَائِنِيِّ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنِ اَلْقَوْمِ يَدْخُلُونَ اَلسَّفِينَةَ يَشْتَرُونَ اَلطَّعَامَ فَيُسَاوِمُونَ مِنْهُ ثُمَّ يَشْتَرِيهِ رَجُلٌ مِنْهُمْ فَيَسْأَلُونَهُ فَيُعْطِيهِمْ مَا يُرِيدُونَ مِنَ اَلطَّعَامِ فَيَكُونُ صَاحِبُ اَلطَّعَامِ هُوَ اَلَّذِي يَدْفَعُهُ إِلَيْهِمْ وَ يَقْبِضُ اَلثَّمَنَ قَالَ "لاَ بَأْسَ مَا أَرَاهُمْ إِلاَّ وَ قَدْ شَارَكُوهُ" فَقُلْتُ إِنَّ صَاحِبَ اَلطَّعَامِ يَدْعُو اَلْكَيَّالَ فَيَكِيلُهُ لَنَا وَ لَنَا أُجَرَاءُ فَيَعْتَبِرُونَهُ فَيَزِيدُ وَ يَنْقُصُ قَالَ "لاَ بَأْسَ مَا لَمْ يَكُنْ شَيْءٌ كَثِيرٌ غَلَطٌ".
It is narrated from Ibn Muskan, from Ishaq Al-Mada'ini, who said: I asked Abu Abdillah عليه السلام about a group of people who board a ship to purchase food. They negotiate the price, and one of them buys it. Then the others request portions of the food from him, and he provides it to them while the seller handles the weighing and receives the payment. Imam عليه السلام said: "There is no harm in this. I do not see it as anything other than them sharing in the purchase." I said: "The seller calls a measurer to weigh it for us, and we have laborers who check the measurement, but sometimes it is slightly more or less." Imam عليه السلام said: "There is no harm in it, as long as the error is not significant."
