"Do not go out to meet the riders, and do not urge someone to cancel a sale he has already agreed upon os as to sell him your own goods, do not artificially inflate prices, and let not a town-dweller sell for a desert-dweller." (Sahih )
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ تَلَقُّوا الرُّكْبَانَ لِلْبَيْعِ وَلاَ يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلاَ تَنَاجَشُوا وَلاَ يَبِيعُ حَاضِرٌ لِبَادٍ
Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah ﷺ said, "Do not let any of you bid against each other."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ
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
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»
"Do not go out to meet the riders, and do not urge someone to cancel a sale he has already agreed upon os as to sell him your own goods, do not artificially inflate prices, and let not a town-dweller sell for a desert-dweller." (Sahih ) (Using translation from Nasāʾī 4496)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَا تَلَقَّوُا الرُّكْبَانَ لِلْبَيْعِ وَلَا يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلَا تَنَاجَشُوا وَلَا يَبِيعُ حَاضِرٌ لِبَادٍ»
