ahmad:4692Yaḥyá > ʿUbaydullāh > Nāfiʿ > Ibn ʿUmar

[Machine] "That the Messenger of Allah ﷺ forbade the practice of shighar (a form of marriage arrangement where a man would marry the daughter of another man and vice versa without a proper dowry). I asked Nafi', 'What is shighar?' He replied, 'It is when a man gives his daughter in marriage and then marries the daughter of the man, and when a man marries his sister-in-law and then marries his own sister-in-law without having to pay a dowry.'"  

أحمد:٤٦٩٢حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللهِ عَنْ نَافِعٍ عَنْ ابْنِ عُمَرَ

أَنَّ رَسُولَ اللهِ ﷺ نَهَى عَنِ الشِّغَارِ قَالَ قُلْتُ لِنَافِعٍ مَا الشِّغَارُ؟ قَالَ يُزَوِّجُ الرَّجُلَ ابْنَتَهُ وَيَتَزَوَّجُ ابْنَتَهُ وَيُزَوِّجُ الرَّجُلَ أُخْتَهُ وَيَتَزَوَّجُ أُخْتَهُ بِغَيْرِ صَدَاقٍ
