وَ رَوَى جَمِيلٌ عَنْ زُرَارَةَ قَالَ: سَأَلْتُ أَبَا جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ اِشْتَرَى تِبْنَ بَيْدَرٍ قَبْلَ أَنْ يُدَاسَ تِبْنَ كُلِّ كُرٍّ بِشَيْءٍ مَعْلُومٍ فَيَأْخُذُ اَلتِّبْنَ وَ يَبِيعُهُ قَبْلَ أَنْ يُكَالَ اَلطَّعَامُ قَالَ "لاَ بَأْسَ بِهِ".
Jameel narrated from Zurara who said: I asked Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (a.s) about a man who purchased straw from a threshing floor before it was threshed, each load of straw for a specified amount, and he took the straw and sold it before the grain was measured. Imam (a.s) said: "There is no harm in it."
