Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 11
وَ سَأَلَهُ جَمِيلٌ: عَمَّنِ اِشْتَرَى تِبْنَ بَيْدَرٍ كُلَّ كُرٍّ بِشَيْءٍ مَعْلُومٍ وَ يَقْبِضُ اَلتِّبْنَ فَيَبِيعُهُ قَبْلَ أَنْ يَكْتَالَ اَلطَّعَامَ فَقَالَ "لاَ بَأْسَ".
Jamil asked Abu Abdillah عليه السلام about a man who buys straw from a threshing floor, each load (kurr) for a specified price, and takes possession of the straw but sells it before measuring the grain. Imam عليه السلام said: "There is no harm in that."
