ذِكْرُ إِحْدَى الْحَالَتَيْنِ اللَّتَيْنِ قَدْ أُبِيحَ هَذَا الْفِعْلُ الْمَزْجُورُ عَنْهُ فِيهِمَا

A man must not make proposal of marriage to a woman when his brother has done so already. And he must not offer a price for a thing for which his brother had already offered a price; and a woman must not be combined in marriage with her father's sister, nor with her mother's sister, and a woman must not ask to have her sister divorced in order to deprive her of what belongs to her, but she must marry, because she will have what Allah has decreed for her. (Using translation from Muslim 1408g)  

عَنِ النَّبِيِّ ﷺ قَالَ لَا يَسُومُ الرَّجُلُ عَلَىسَوْمِ أَخِيهِ وَلَا يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ  

[Machine] On the authority of the Prophet ﷺ , he said: "A man should not outbid his brother's bidding, nor propose to a woman who has already been proposed to."  

عَنِ النَّبِيِّ ﷺ قَالَ لَا يَسْتَامُ الرَّجُلُ عَلَى سَوْمِ أَخِيهِ وَلَا يَخْطُبُ عَلَى خِطْبَتِهِ  

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 يَسْتَامُ الرَّجُلُ عَلَى سَوْمِ أَخِيهِ وَلَا يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ
