During the time of Messenger of Allah ﷺ we used to buy grain, and he sent a man to us who ordered us to move it from the spot where we had bought it to some other place, before we sold it without weighing or measuring it. (Using translation from Abū Dāʾūd 3493)   

كُنَّا فِي زَمَانِ رَسُولِ اللهِ ﷺ نَبْتَاعُ الطَّعَامَ فَيَبْعَثُ عَلَيْنَا مَنْ يَأْمُرُنَا بِانْتِقَالِهِ مِنَ الْمَكَانِ الَّذِي ابْتَعْنَاهُ إِلَى مَكَانٍ سِوَاهُ قَبْلَ أَنْ نَبِيعَهُ  

[Machine] The Messenger of Allah ﷺ said, "Whoever purchases food should not sell it until he receives it." He said, "We used to buy food from the caravans and the Prophet ﷺ prohibited us from selling it until we transported it from its place."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنِ اشْتَرَى طَعَامًا فَلَا يَبِعْهُ حَتَّى يَسْتَوْفِيَهُ قَالَ وَكُنَّا نَشْتَرِي الطَّعَامَ مِنَ الرُّكْبَانِ جُزَافًا فَنَهَانَا رَسُولُ اللهِ ﷺ أَنْ نَبِيعَهُ حَتَّى نَنْقُلَهُ مِنْ مَكَانِهِ  

[Machine] I saw people in the time of the Messenger of Allah ﷺ when they exchanged food, they would strike a deal to sell their places until they found shelter in their tents.  

رَأَيْتُ النَّاسَ فِي عَهْدِ رَسُولِ اللهِ ﷺ إِذَا تَبَايَعُوا الطَّعَامَ جُزَافًا يُضْرَبُونَ فِي أَنْ يَبِيعُوا مَكَانَهُمْ حَتَّى يُؤْوُوهُ إِلَى رِحَالِهِمْ  

I bought olive oil in the market. When I became its owner, a man met me and offered good profit for it. I intended to settle the bargain with him, but a man caught hold of my hand from behind. When I turned I found that he was Zayd ibn Thabit. He said: Do not sell it on the spot where you have bought it until you take it to your house, for the Messenger of Allah ﷺ forbade to sell the goods where they are bought until the tradesmen take them to their houses. (Using translation from Abū Dāʾūd 3499)   

ابْتَعْتُ زَيْتًا فِي السُّوقِ فَلَمَّا اسْتَوْفَيْتُ لَقِيَنِي رَجُلٌ فَأَعْطَانِي رِبْحًا حَسَنًا فَأَرَدْتُ أَنْ أَضْرِبَ عَلَى يَدِهِ فَأَخَذَ رَجُلٌ بِرِدَائِي مِنْ خَلْفِي فَالْتَفَتُّ إِلَيْهِ فَإِذَا زَيْدُ بْنُ ثَابِتٍ فَقَالَ لَا تَبِعْهُ حَيْثُ ابْتَعْتَهُ حَتَّى تَحُوزَهُ إِلَى رَحْلِكَ؛ فَإِنَّ رَسُولَ اللهِ ﷺ نَهَى أَنْ تُبَاعَ السِّلْعَةُ حَيْثُ تَبْتَاعُ حَتَّى يَحُوزَهَا التُّجَّارُ إِلَى رِحَالِهِمْ
