The Prophet ﷺ said, "The buyer of foodstuff should not sell it before it has been measured for him." Ismaʿil narrated instead, "He should not sell it before receiving it."
أَنَّ النَّبِيَّ ﷺ قَالَ مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ زَادَ إِسْمَاعِيلُ مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَقْبِضَهُ
