"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." (Using translation from Nasāʾī 4600)
قَالَ رَسُولُ اللهِ ﷺ مَنِ ابْتَاعَ طَعَامًا فَلَا يَبِعْهُ حَتَّى يَقْبِضَهُ قَالَ قَالَ ابْنُ عَبَّاسٍ أَحْسِبُ كُلَّ شَيْءٍ بِمَنْزِلَةِ الطَّعَامِ
