It is invalid to sell goods before taking possession of them
Sahih Muslim
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ عُبَيْدِ اللَّهِ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا أَبِي، حَدَّثَنَا عُبَيْدُ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ، عُمَرَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنِ اشْتَرَى طَعَامًا فَلاَ يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ" . قَالَ وَكُنَّا نَشْتَرِي الطَّعَامَ مِنَ الرُّكْبَانِ جِزَافًا فَنَهَانَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ نَبِيعَهُ حَتَّى نَنْقُلَهُ مِنْ مَكَانِهِ .
Ibn Umar (Allah be pleased with them) reported Allah's Messenger (ﷺ) as saying: He who buys foodgrain should not sell that before taking possession of it. He (the narrator) said: We used to buy foodgrain from the caravans in bulk, but Allah's Messenger (ﷺ) forbade us to re-sell that until we had shifted it to some other place.
