96) Chapter: If A Man Sells An Item And A Third Party Has More Right To It
It was narrated from Sammurah that the Messenger of Allah said:
"If a woman is married off by two guardians, then the first marriage is the one that counts, and if a man sells something to two men, it belongs to the first one."
96) باب الرَّجُلِ يَبِيعُ السِّلْعَةَ فَيَسْتَحِقُّهَا مُسْتَحِقٌّ
أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا غُنْدَرٌ، عَنْ شُعْبَةَ، عَنْ قَتَادَةَ، عَنِ الْحَسَنِ، عَنْ سَمُرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ . " أَيُّمَا امْرَأَةٍ زَوَّجَهَا وَلِيَّانِ فَهِيَ لِلأَوَّلِ مِنْهُمَا وَمَنْ بَاعَ بَيْعًا مِنْ رَجُلَيْنِ فَهُوَ لِلأَوَّلِ مِنْهُمَا "
