وَحَدَّثَنِي، عَنْ مَالِك، عَنِ
ابْنِ شِهَابٍ ، عَنْ
عَمْرِو بْنِ الشَّرِيدِ ، أَنَّ
عَبْدَ اللَّهِ بْنَ عَبَّاسٍ سُئِلَ عَنْ رَجُلٍ كَانَتْ لَهُ امْرَأَتَانِ، فَأَرْضَعَتْ إِحْدَاهُمَا غُلَامًا، وَأَرْضَعَتِ الْأُخْرَى جَارِيَةً، فَقِيلَ لَهُ : هَلْ يَتَزَوَّجُ الْغُلَامُ الْجَارِيَةَ ؟ فَقَالَ : " لَا،
اللِّقَاحُ وَاحِدٌ "
It is narrated from Amr bin Shuraid that a question was asked to Sayyiduna Abdullah bin Abbas (may Allah be pleased with them): If a man has two wives, and one wife breastfeeds a boy and the other wife breastfeeds a girl, is the marriage between that boy and girl permissible? He replied: It is not permissible because both have the same father.
