حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ ‏"‏ ‏.‏

Narrated Ibn 'Abbas

The Messenger of Allah (ﷺ) as saying: If anyone buys grain, he should not sell it until he measures it. Abu Bakr added in his version: I asked Ibn 'Abbas: Why ? He replied: Do you not see that they sell (grain) for gold, but the grain is still with the seller.
