Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 27
وَ سَأَلَهُ أَبُو اَلصَّبَّاحِ اَلْكِنَانِيُّ: عَنْ رَجُلٍ اِشْتَرَى مِنْ رَجُلٍ مِائَةَ مَنٍّ صُفْراً بِكَذَا وَ كَذَا وَ لَيْسَ عِنْدَهُ مَا اُشْتُرِيَ مِنْهُ فَقَالَ "لاَ بَأْسَ إِذَا أَوْفَاهُ اَلْوَزْنَ اَلَّذِي اُشْتُرِطَ عَلَيْهِ".
Abu al-Sabbah al-Kinani asked Imam عليه السلام about a man who bought one hundred mann of brass for a specified price, while the seller did not possess the quantity sold at the time of the transaction. Imam عليه السلام said: "There is no harm as long as he delivers the specified weight that was agreed upon."
