رَوَى مَنْصُورُ بْنُ حَازِمٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: "إِذَا اِشْتَرَيْتَ مَتَاعاً فِيهِ كَيْلٌ أَوْ وَزْنٌ فَلاَ تَبِعْهُ حَتَّى تَقْبِضَهُ إِلاَّ أَنْ تُوَلِّيَهُ فَإِنْ لَمْ يَكُنْ فِيهِ كَيْلٌ وَ لاَ وَزْنٌ فَبِعْهُ ".
Mansur ibn Hazim narrated from Abu Abdillah عليه السلام who said: "If you purchase goods that require measuring or weighing, do not sell them until you take possession of them - unless you appoint someone to take possession on your behalf. However, if the goods do not require measuring or weighing, then you may sell them immediately."
