Prohibition and invalidity of Shighar Marriage
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا ابْنُ نُمَيْرٍ، وَأَبُو أُسَامَةَ عَنْ عُبَيْدِ اللَّهِ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الشِّغَارِ . زَادَ ابْنُ نُمَيْرٍ وَالشِّغَارُ أَنْ يَقُولَ الرَّجُلُ لِلرَّجُلِ زَوِّجْنِي ابْنَتَكَ وَأُزَوِّجُكَ ابْنَتِي أَوْ زَوِّجْنِي أُخْتَكَ وَأُزَوِّجُكَ أُخْتِي .
Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (ﷺ) prohibited Shighar. Ibn Numair added: Shighar means that a person should say to the other person: Give me the hand of your daughter in marriage and I will (in return) marry my daughter to you; or merry me your sister, and I will marry my sister to you.
