لم يجز للمشتري منه أن يبيعه ولا يأكله حتى يعيد الكيل والوزن
Translation: The subsequent buyer may neither resell nor eat it before repeating the measure or weight.
Repeated measurement or weighing is not merely bookkeeping. It secures the contracted quantity and the legally effective delivery to the second purchaser. Commentaries also discuss the possibility of an excess remaining owed to an earlier entitled party.
In this specific measured-sale situation, the second purchaser may neither resell nor consume the goods until the fresh measurement or weighing is accomplished.
