Messenger of Allah ﷺ said, "You should not try to cancel the purchases of one another (to get a benefit thereof), and do not go ahead to meet the caravan (for buying the goods) (but wait) till it reaches the market."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلاَ تَلَقَّوُا السِّلَعَ حَتَّى يُهْبَطَ بِهَا إِلَى السُّوقِ  

The Messenger of Allah ﷺ as saying: None of you must buy in opposition to one another ; and do not go out to meet the merchandise, (but one must wait) till it is brought down to the market.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلاَ تَلَقَّوُا السِّلَعَ حَتَّى يُهْبَطَ بِهَا الأَسْوَاقَ  

One amongst you should not enter into a transaction when another is bargaining. (Using translation from Muslim 1412e)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلَا يَبِعْ حَاضِرٌ لِبَادٍ وَلَا تَنَاجَشُوا وَلَا تَلَقَّوْا السِّلَعَ  

[Machine] The Prophet ﷺ forbade receiving goods until they are brought down to the markets and he forbade cheating. He said, "None of you should sell his goods over the sale of another."  

أَنَّ النَّبِيَّ ﷺ نَهَى عَنْ تَلَقِّي السِّلَعِ حَتَّى يُهْبَطَ بِهَا الْأَسْوَاقُ وَنَهَى عَنِ النَّجْشِ وَقَالَ لَا يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ  

One amongst you should not enter into a transaction when another is bargaining. (Using translation from Muslim 1412e)  

قَالَ رَسُولُ اللَّهِ ﷺ «لَا يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلَا تَلَقَّوْا السِّلَعَ حَتَّى يُهْبَطَ بِهَا الْأَسْوَاقَ وَلَا تَنَاجَشُوا»
