A person should not enter into a transaction when his brother (had already entered into but not finalised), and he should not make proposal of marriage upon the proposal already made by his brother, until he permits it.  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَبِعِ الرَّجُلُ عَلَى بَيْعِ أَخِيهِ وَلاَ يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ إِلاَّ أَنْ يَأْذَنَ لَهُ  

A person should not enter into a transaction when his brother is already making a transaction and he should not make a proposal of marriage when his brother has already made a proposal except when he gives permission.

Abu Hurairah reported the Apostle of Allaah ﷺ as saying “ A man should not seek the hand of a woman in marriage when his brother has already sought her hand.”  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَخْطُبُ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ  

the Messenger of Allah said: “A man should not propose to a woman to whom his brother has already proposed.”  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَخْطُبِ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَخْطُبِ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ  

[Machine] The Messenger of Allah ﷺ forbade a man from proposing to the same woman his brother has previously proposed to, unless the first proposer gives up his right or gives permission.  

نَهَى رَسُولُ اللهِ ﷺ أَنْ يَخْطُبَ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ حَتَّى يَدَعَهَا الَّذِي خَطَبَهَا أَوَّلَ مَرَّةٍ أَوْ 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»  

[Machine] "From the Prophet of Allahﷺ he said, 'A man should not propose to his brother's betrothed until the first proposer either abandons his proposal or gives permission to the second proposer to proceed.'"  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ «لَا يَخْطُبُ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ حَتَّى يَتْرُكَ الْخَاطِبُ الْأَوَّلُ أَوْ يَأْذَنَ لَهُ فَيَخْطُبُ»  

Abu Hurairah reported the Apostle of Allaah ﷺ as saying “ A man should not seek the hand of a woman in marriage when his brother has already sought her hand.” (Using translation from Abū Dāʾūd 2080)  

قَالَ رَسُولُ اللهِ ﷺ «لَا يَخْطُبِ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ»  

[Machine] The Messenger of Allah ﷺ prohibited a man from proposing to the sister of his brother until he is rejected or given permission.  

نَهَى رَسُولُ اللهِ ﷺ أَنْ يَخْطُبَ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ حَتَّى يَرُدَّ أَوْ يَأْذَنَ لَهُ  

"لا يَبِيع الرَّجُلُ عَلَى بَيعِ أَخِيهِ، وَلا يَخْطُب عَلَى خِطْبَةِ أَخيهِ إِلا أَنْ يَأذَنَ لَهُ".
