يَحْيَى بْنُ يَحْيَى ، قَالَ : قَرَأْتُ عَلَى
مَالِكٍ ، عَنْ
نَافِعٍ ، عَنِ
ابْنِ عُمَرَ : " أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنِ الشِّغَارِ وَالشِّغَارُ : أَنْ يُزَوِّجَ الرَّجُلُ ابْنَتَهُ ، عَلَى أَنْ يُزَوِّجَهُ ابْنَتَهُ ، وَلَيْسَ بَيْنَهُمَا صَدَاقٌ " ،
Ibn 'Umar (RA) said that Allah's Messenger (ﷺ) prohibited Shighar which means that a man gives his daughter in marriage on the condition that the other gives his daughter to him in marriage without any dower being paid by either.
