"The Messenger of Allah ﷺ said: 'Whoever buys food, let him not sell it until he has taken full possession of it.'" (Sahih) In his narration, (one of the narrators) Abu 'Awanah said: "Ibn 'Abbas said: 'I think everything is like food."'
قَالَ رَسُولُ اللَّهِ ﷺ مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ قَالَ أَبُو عَوَانَةَ فِي حَدِيثِهِ قَالَ ابْنُ عَبَّاسٍ وَأَحْسِبُ كُلَّ شَىْءٍ مِثْلَ الطَّعَامِ
