Sunan Abu Dawud · Hadith 3492
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 'Umar:The Messenger of Allah (ﷺ) as saying: If anyone buys grain, he must not sell it till receives it in full
