The Messenger of Allah ﷺsaid: “Whoever buys foodstuff should not sell it until he takes possession of all of it.” (Using translation from Aḥmad 396)   

أحمد:٨٤٤٠ – حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ حَدَّثَنِي الضَّحَّاكُ بْنُ عُثْمَانَ فِي سَنَةِ إِحْدَى وَخَمْسِينَ خَرَجْتُ مَعَ سُفْيَانَ قَالَ حَدَّثَنِي بُكَيْرُ بْنُ عَبْدِ اللهِ بْنِ الْأَشَجِّ عَنْ سُلَيْمَانَ بْنِ يَسَارٍ عَنْ أَبِي هُرَيْرَةَ قَالَ

قَالَ رَسُولُ اللهِ ﷺ مَنِ اشْتَرَى طَعَامًا فَلَا يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ
