Messenger of Allah ﷺ said, "Do not urge somebody to return what he has already bought (i.e. in optional sale) from another seller so as to sell him your own goods."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ أَخِيهِ  

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  

None amongst you should outbid another in a transaction, nor should he make proposals of marriage upon the proposal made by someone else.  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلاَ يَخْطُبْ بَعْضُكُمْ عَلَى خِطْبَةِ بَعْضٍ  

One amongst you should not enter into a transaction when another is bargaining.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ  

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  

"Let one of you not undersell another."[1]  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَبِيعُ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ  

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  

[Machine] According to the Messenger of Allah ﷺ , he said, "None of you should sell based on the sale of another, nor should anyone propose marriage to someone who has already been proposed to."  

عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ لَا يَبِيعُ بَعْضُكُمْعَلَى بَيْعِ بَعْضٍ وَلَا يَخْطُبُ عَلَى خِطْبَةِ بَعْضٍ  

[Machine] The Messenger of Allah ﷺ said, "None of you should sell the property of his brother without his permission."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا يَبِعْ أَحَدُكُمْ عَلَى بَيْعِ أَخِيهِ إِلَّا بِإِذْنِهِ»  

Messenger of Allah ﷺ said, "Do not urge somebody to return what he has already bought (i.e. in optional sale) from another seller so as to sell him your own goods." (Using translation from Bukhārī 2139)   

عَنِ النَّبِيِّ ﷺ قَالَ «لَا يَبِيعُ أَحَدُكُمْ عَلَى بَيْعِ بَعْضٍ»  

"لا يَبِيع بَعْضُكُمْ عَلَى بيعِ أخِيهِ".
