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 5143
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ ، حَدَّثَنَا اللَّيْثُ ، عَنْ جَعْفَرِ بْنِ رَبِيعَةَ ، عَنْ الْأَعْرَجِ ، قَالَ : قَالَ أَبُو هُرَيْرَةَ يَأْثُرُ : عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " إِيَّاكُمْ وَالظَّنَّ ، فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ ، وَلَا تَجَسَّسُوا ، وَلَا تَحَسَّسُوا ، وَلَا تَبَاغَضُوا ، وَكُونُوا إِخْوَانًا .
Narrated Abu Huraira: The Prophet said, "Beware of suspicion (about others), as suspicion is the falsest talk, and do not spy upon each other, and do not listen to the evil talk of the people about others' affairs, and do not have enmity with one another, but be brothers.
