Messenger of Allah ﷺ forbade the selling of things by a town dweller on behalf of a desert dweller; and similarly Najsh was forbidden. And one should not urge somebody to return the goods to the seller so as to sell him his own goods; nor should one demand the hand of a girl who has already been engaged to someone else; and a woman should not try to cause some other woman to be divorced in order to take her place.  

نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَبِيعَ حَاضِرٌ لِبَادٍ وَلاَ تَنَاجَشُوا وَلاَ يَبِيعُ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلاَ يَخْطُبُ عَلَى خِطْبَةِ أَخِيهِ وَلاَ تَسْأَلُ الْمَرْأَةُ طَلاَقَ أُخْتِهَا لِتَكْفَأَ مَا فِي إِنَائِهَا  

The Prophet ﷺ said, "No town-dweller should sell for a bedouin. Do not practice Najsh (i.e. Do not offer a high price for a thing which you do not want to buy, in order to deceive the people). No Muslim should offer more for a thing already bought by his Muslim brother, nor should he demand the hand of a girl already engaged to another Muslim. A Muslim woman shall not try to bring about The divorce of her sister (i.e. another Muslim woman) in order to take her place herself."  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَبِيعُ حَاضِرٌ لِبَادٍ وَلاَ تَنَاجَشُوا وَلاَ يَزِيدَنَّ عَلَى بَيْعِ أَخِيهِ وَلاَ يَخْطُبَنَّ عَلَى خِطْبَتِهِ وَلاَ تَسْأَلِ الْمَرْأَةُ طَلاَقَ أُخْتِهَا لِتَسْتَكْفِئَ إِنَاءَهَا  

Do not outbid in a sale in order to ensnare. No man should enter into a transaction in which his brother has already entered, and no dweller of the town should sell on behalf of the villager. And no man should make a proposal of marriage which his brother has already made and no woman should ask for the divorce of another (co-wife) in order to deprive her of what belongs to her.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَنَاجَشُوا وَلاَ يَبِعِ الْمَرْءُ عَلَى بَيْعِ أَخِيهِ وَلاَ يَبِعْ حَاضِرٌ لِبَادٍ وَلاَ يَخْطُبِ الْمَرْءُ عَلَى خِطْبَةِ أَخِيهِ وَلاَ تَسْأَلِ الْمَرْأَةُ طَلاَقَ الأُخْرَى لِتَكْتَفِئَ مَا فِي إِنَائِهَا  

The Messenger of Allah said: "No town-dweller should sell for a desert-dweller, do not artificially inflate prices, no man should urge a seller to cancel a sale already agreed upon with another buy so as to by the goods himself, no one should make a proposal over the proposal of his brother and no woman should make a proposal over the proposal of his brother and no woman should ask for her sister in faith) to be divorced so as to turn over what is in her vessel Deprived her of her share of maintenance) and so that she may get married in her place: she will have what Allah has decreed or her."  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَبِيعَنَّ حَاضِرٌ لِبَادٍ وَلاَ تَنَاجَشُوا وَلاَ يُسَاوِمِ الرَّجُلُ عَلَى سَوْمِ أَخِيهِ وَلاَ يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ وَلاَ تَسْأَلِ الْمَرْأَةُ طَلاَقَ أُخْتِهَا لِتَكْتَفِئَ مَا فِي إِنَائِهَا وَلِتُنْكَحَ فَإِنَّمَا لَهَا مَا كَتَبَ اللَّهُ لَهَا  

"I heard the messenger of Allah say: "No man should urge anyone to cancel a sale he has already agreed upon with his brother so as to sell him his own goods; no town-dweller should sell for a desert-dweller; do not artificially inflate prices; no man should outbid his brother; and no woman should ask for her sister (in faith) to be divorced so as to turn over what is in her vessel (deprive her of her share of maintenance),  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ يَبِيعُ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلاَ يَبِيعُ حَاضِرٌ لِبَادٍ وَلاَ تَنَاجَشُوا وَلاَ يَزِيدُ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلاَ تَسْأَلِ الْمَرْأَةُ طَلاَقَ الأُخْرَى لِتَكْتَفِئَ مَا فِي إِنَائِهَا  

"No tow-dweller should sell for desert-dweller, no man should outbid his brother; and no woman should ask for her sister (in faith) to be divorced so as to turn over what is in her bowl (deprive her of her share of maintenance)"  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَبِيعُ حَاضِرٌ لِبَادٍ وَلاَ تَنَاجَشُوا وَلاَ يَزِيدُ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلاَ تَسْأَلُ الْمَرْأَةُ طَلاَقَ أُخْتِهَا لِتَسْتَكْفِئَ بِهِ مَا فِي صَحْفَتِهَا  

It was narrated that Abu Hurairah said: "The Messenger of Allah said: 'Do not artificially inflate prices, a resident should not sell for a Bedouin, a man should not offer more for something that has already been bought by his brother, no one should propose marriage to a woman when someone else has already proposed to her, and no woman should try to bring about the divorce of her sister, in order to deprive her of the blessings that she has.'"  

قَالَ رَسُولُ اللَّهِ ﷺ وَقَالَ مُحَمَّدٌ عَنِ النَّبِيِّ ﷺ لاَ تَنَاجَشُوا وَلاَ يَبِعْ حَاضِرٌ لِبَادٍ وَلاَ يَبِعِ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلاَ يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ وَلاَ تَسْأَلِ الْمَرْأَةُ طَلاَقَ أُخْتِهَا لِتَكْتَفِئَ مَا فِي إِنَائِهَا  

It was narrated that Abu Hurairah said: "The Messenger of Allah said: 'Do not artificially inflate prices, a resident should not sell for a Bedouin, a man should not offer more for something that has already been bought by his brother, no one should propose marriage to a woman when someone else has already proposed to her, and no woman should try to bring about the divorce of her sister, in order to deprive her of the blessings that she has.'" (Using translation from Nasāʾī 3239)   

قَالَ رَسُولُ اللهِ ﷺ لَا يَبِيعُ حَاضِرٌ لِبَادٍ وَلَا تَنَاجَشُوا وَلَا يَزِيدُ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلَا يَخْطُبُ عَلَى خِطْبَتِهِ وَلَا تَسْأَلُ امْرَأَةٌ طَلَاقَ أُخْتِهَا  

[Machine] The Prophet ﷺ prohibited selling an item that someone else already intended to buy, or competing with someone in a transaction, or a man proposing marriage to a woman who has already been proposed to by his brother, or selling something that belongs to his brother. A woman should not ask her sister for a divorce just to take what is in her dowry or her utensils; instead, she should marry, for her sustenance is from Allah.  

أَنَّ النَّبِيَّ ﷺ نَهَى أَنْ يَبِيعَ حَاضِرٌ لِبَادٍ أَوْ يَتَنَاجَشُوا أَوْ يَخْطُبَ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ أَوْ يَبِيعَ عَلَى بَيْعِ أَخِيهِ وَلَا تَسْأَلِ الْمَرْأَةُ طَلَاقَ أُخْتِهَا لِتَكْتَفِئَ مَا فِي صَحْفَتِهَا أَوْ إِنَائِهَا وَلْتَنْكِحْ فَإِنَّمَا رِزْقُهَا عَلَى اللهِ  

The Messenger of Allah said: "No town-dweller should sell for a desert-dweller, do not artificially inflate prices, no man should urge a seller to cancel a sale already agreed upon with another buy so as to by the goods himself, no one should make a proposal over the proposal of his brother and no woman should make a proposal over the proposal of his brother and no woman should ask for her sister in faith) to be divorced so as to turn over what is in her vessel Deprived her of her share of maintenance) and so that she may get married in her place: she will have what Allah has decreed or her." (Using translation from Nasāʾī 4502)  

قَالَ رَسُولُ اللهِ ﷺ لَا يَبِيعُ حَاضِرٌ لِبَادٍ وَلَا تَنَاجَشُوا وَلَا يُسَاوِمِ الرَّجُلُ عَلَى سَوْمِ أَخِيهِ وَلَا يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ وَلَا تَسْأَلِ الْمَرْأَةُ طَلَاقَ أُخْتِهَا لِتَكْتَفِئَ مَا فِي إِنَائِهَا وَلِتُنْكَحَ فَإِنَّمَا لَهَا مَا كَتَبَ اللهُ لَهَا  

"لا يَبِعْ حَاضِرٌ لِبَادٍ، وَلا تَنَاجَشُوا، وَلا يَبِيع الرَّجُلُ عَلَى بَيعِ أَخيه، وَلا يَخْطب عَلى خِطْبةِ أَخِيهِ، وَلا تَسْأَل الْمَرْأَةُ طَلاق أُخْتِهَا لِتَكْفَأْ مَا فِي إِنَائِهَا [ولِتَنْكَحَ، فَإنَّمَا لَهَا مَا كَتبَ اللهُ لَهَا] ".
