صحيح البخاري
Sahih Bukhari
كتاب النكاح
The Book of (The Wedlock)
بَابُ لاَ يَخْطُبُ عَلَى خِطْبَةِ أَخِيهِ، حَتَّى يَنْكِحَ أَوْ يَدَعَ:
(46) Chapter. None should ask for the hand of a lady who is already engaged to his brother (Muslim), but one should wait till the first suitor marries her or leaves her.
Hadith 5142
حَدَّثَنَا مَكِّيُّ بْنُ إِبْرَاهِيمَ ، حَدَّثَنَا ابْنُ جُرَيْجٍ ، قَالَ : سَمِعْتُ نَافِعًا يُحَدِّثُ أَنَّ ابْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا ، كَانَ يَقُولُ : " نَهَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يَبِيعَ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ ، وَلَا يَخْطُبَ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ حَتَّى يَتْرُكَ الْخَاطِبُ قَبْلَهُ ، أَوْ يَأْذَنَ لَهُ الْخَاطِبُ " .
Narrated Ibn `Umar: The Prophet decreed that one should not try to cancel a bargain already agreed upon between some other persons (by offering a bigger price). And a man should not ask for the hand of a girl who is already engaged to his Muslim brother, unless the first suitor gives her up, or allows him to ask for her hand.
