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  

"No one of you should urge someone to cancel a sale he has already agreed upon with his brother so as to sell him his own goods."  

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لاَ يَبِيعُ أَحَدُكُمْ عَلَى بَيْعِ أَخِيهِ  

The Prophet ﷺ said: One of you must not ask a woman in marriage when his brother has done so already, and one of you must not sell (his own goods) when his brother has already sold (his goods) except with his permission.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَخْطُبُ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ وَلاَ يَبِيعُ عَلَى بَيْعِ أَخِيهِ إِلاَّ بِإِذْنِهِ  

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  

Yahya related to me from Malik from Muhammad ibn Yahya ibn Habban from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "Do not ask for a woman in marriage when another muslim has already done so."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَخْطُبُ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ  

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah ﷺ said, "Do not ask for a woman in marriage when another muslim has already done so." Malik said, "The explanation of the statement of the Messenger of Allah ﷺ according to what we think - and Allah knows best - is that 'Do not ask for a woman in marriage when another muslim has already done so' means that when a man has asked for a woman in marriage, and she has inclined to him and they have agreed on a bride-price, which she has suggested and with which they are mutually satisfied, it is forbidden for another man to ask for that woman in marriage. It does not mean that when a man has asked for a woman in marriage, and his suit does not agree with her and she does not incline to him that no one else can ask for her in marriage. That is a door to misery for people."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَخْطُبُ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ۔ قَالَ مَالِكٌ : وَتَفْسِيرُ قَوْلِ رَسُولِ اللهِ ﷺ فِيمَا نُرَى - وَاللهُ أَعْلَمُ - «لَا يَخْطُبُ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ»: أَنْ يَخْطُبَ الرَّجُلُ الْمَرْأَةَ، فَتَرْكَنَ إِلَيْهِ، وَيَتَّفِقَانِ عَلَى صَدَاقٍ وَاحِدٍ مَعْلُومٍ، وَقَدْ تَرَاضَيَا، فَهِيَ تَشْتَرِطُ عَلَيْهِ لِنَفْسِهَا، فَتِلْكَ الَّتِي نُهِيَ أَنْ يَخْطُبَهَا الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ. وَلَمْ يَعْنِ بِذلِكَ، إِذَا خَطَبَ الرَّجُلُ الْمَرْأَةَ، فَلَمْ يُوَافِقْهَا أَمْرُهُ، وَلَمْ تَرْكَنْ إِلَيْهِ، أَنْ لَا يَخْطُبَهَا أَحَدٌ، فَهذَا بَابُ فَسَادٍ يَدْخُلُ عَلَى النَّاسِ.  

The Prophet ﷺ said: One of you must not ask a woman in marriage when his brother has done so already, and one of you must not sell (his own goods) when his brother has already sold (his goods) except with his permission. (Using translation from Abū Dāʾūd 2081)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَخْطُبُ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ وَلَا يَبِيعُ عَلَى بَيْعِ أَخِيهِ إِلَّا بِإِذْنِهِ  

[Machine] Ibn Umar narrated that the Messenger of Allah ﷺ prohibited any of you from selling over the sale of his brother, except for spoils of war and inheritances.  

ابْنُ عُمَرَ نَهَى رَسُولُ اللهِ ﷺ أَنْ يَبِيعَ أَحَدُكُمْ عَلَى بَيْعِ أَخِيهِ إِلَّا الْغَنَائِمَ وَالْمَوَارِيثَ  

[Machine] The Prophet ﷺ said, "None of you should sell upon the sale of his brother, nor propose to marry the betrothed of his brother, unless he gives permission."  

عَنِ النَّبِيِّ ﷺ قَالَ لَا يَبِعْ أَحَدُكُمْ عَلَى بَيْعِ أَخِيهِ وَلَا يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ إِلَّا أَنْ يَأْذَنَ لَهُ  

The Prophet ﷺ said: One of you must not ask a woman in marriage when his brother has done so already, and one of you must not sell (his own goods) when his brother has already sold (his goods) except with his permission. (Using translation from Abū Dāʾūd 2081)   

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا يَخْطُبُ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ وَلَا يَبِيعُ عَلَى بَيْعِ أَخِيهِ حَتَّى يَأْذَنَ لَهُ»  

It was narrated from Abu Hurairah that the Prophet said: "None of you should propose marriage to a woman when someone else has already proposed to her." (Using translation from Nasāʾī 3240)   

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا يَخْطُبْ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ»  

"Let one of you not undersell another."[1] (Using translation from Ibn Mājah 2171)  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ»  

[Machine] The Messenger of Allah ﷺ said, "None of you should sell upon the sale of his brother, nor propose marriage upon his engagement."  

عَنْ رَسُولِ اللهِ ﷺ قَالَ «لَا يَبْتَاعُ أَحَدُكُمْ عَلَى بَيْعِ أَخِيهِ وَلَا يَخْطُبُ عَلَى خِطْبَتِهِ»
