Narrated by:Abu Hurairah said
It was narrated that Abu Hurairah said:"The Messenger of Allah forbade Ash-Shighar." (One of the narrators) 'Ubaidullah said: "Ash-Shighar means when a man gives his daughter in marriage on condition that (the other man) gives him his sister in marriage."
أَخْبَرَنَا مُحَمَّدُ بْنُ إِبْرَاهِيمَ، وَعَبْدُ الرَّحْمَنِ بْنُ مُحَمَّدِ بْنِ سَلاَّمٍ، قَالاَ حَدَّثَنَا إِسْحَاقُ الأَزْرَقُ، عَنْ عُبَيْدِ اللَّهِ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الشِّغَارِ . قَالَ عُبَيْدُ اللَّهِ وَالشِّغَارُ كَانَ الرَّجُلُ يُزَوِّجُ ابْنَتَهُ عَلَى أَنْ يُزَوِّجَهُ أُخْتَهُ .
