The prohibition of proposing marriage when one's brother has already proposed, unless he gives permission or gives up the idea

باب تَحْرِيمِ الْخِطْبَةِ عَلَى خِطْبَةِ أَخِيهِ حَتَّى يَأْذَنَ أَوْ يَتْرُكَ ‏‏

Sahih Muslim 1412a
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح وَحَدَّثَنَا ابْنُ رُمْحٍ، أَخْبَرَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ ‏ ‏.‏
"‏ لاَ يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ وَلاَ يَخْطُبْ بَعْضُكُمْ عَلَى خِطْبَةِ بَعْضٍ ‏"
Ibn Umar (Allah be pleased with them) reported Allah's Apostle (ﷺ) as having said this:

None amongst you should outbid another in a transaction, nor should he make proposals of marriage upon the proposal made by someone else.
