أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، وَالْحَارِثُ بْنُ مِسْكِينٍ، قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ، عَنِ ابْنِ الْقَاسِمِ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ ‏"‏ ‏.‏

Hakim bin Hizam said

"I bought some food and made food and made a profit on it (by selling it) before I took possession of it. I came to the Messenger of Allah and told him about that and he said: 'Do not sell it until you take possession of it."'
