That the Prophet ﷺ said: "Whoever buys food, then he is not to sell it until he takes possession of it." Ibn 'Abbas said: "All things are considered the same (in this regard)." [He said:] There are narrations on this topic from Jabir, Ibn 'Umar, and Abu Hurairah.
أَنَّ النَّبِيَّ ﷺ قَالَ مَنِ ابْتَاعَ طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ قَالَ ابْنُ عَبَّاسٍ وَأَحْسِبُ كُلَّ شَيْءٍ مِثْلَهُ قَالَ وَفِي الْبَابِ عَنْ جَابِرٍ وَابْنِ عُمَرَ وَأَبِي هُرَيْرَةَ
"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
"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
