The Muslim should not purchase in opposition to his brother, and he should not make the proposal of marriage on the proposal already made by his brother.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَسُمِ الْمُسْلِمُ عَلَى سَوْمِ أَخِيهِ وَلاَ يَخْطُبْ عَلَى خِطْبَتِهِ
A Muslim should not purchase (in opposition) to his brother.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَسُمِ الْمُسْلِمُ عَلَى سَوْمِ أَخِيهِ
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."
أَنَّ النَّبِيَّ ﷺ قَالَ لاَ يَخْطُبْ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ
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.
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)
