It was narrated that Ibn 'Abbas said:

"The Messenger of Allah said: 'Whoever buys food let him not sell it until he takes possession of it. Ibn 'Abbas said: "I think the same applies to everything else as to food."

أَخْبَرَنَا مُحَمَّدُ بْنُ رَافِعٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، قَالَ حَدَّثَنَا مَعْمَرٌ، عَنِ ابْنِ طَاوُسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِيعُهُ حَتَّى يَقْبِضَهُ " . قَالَ ابْنُ عَبَّاسٍ فَأَحْسَبُ أَنَّ كُلَّ شَىْءٍ بِمَنْزِلَةِ الطَّعَامِ .
