Sunan at-Tirmithiy كتاب الرضاع باب ما جاء فى لبن الفحل
حَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا مَالِكٌ ح وَحَدَّثَنَا الأَنْصَارِىُّ حَدَّثَنَا مَعْنٌ قَالَ حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ عَنِ ابْنِ شِهَابٍ عَنْ عَمْرِو بْنِ الشَّرِيدِ عَنِ ابْنِ عَبَّاسٍ أَنَّهُ سُئِلَ عَنْ رَجُلٍ لَهُ جَارِيَتَانِ أَرْضَعَتْ إِحْدَاهُمَا جَارِيَةً وَالأُخْرَى غُلاَمًا أَيَحِلُّ لِلْغُلاَمِ أَنْ يَتَزَوَّجَ بِالْجَارِيَةِ فَقَالَ لاَ اللِّقَاحُ وَاحِدٌ. قَالَ أَبُو عِيسَى وَهَذَا تَفْسِيرُ لَبَنِ الْفَحْلِ وَهَذَا الأَصْلُ فِى هَذَا الْبَابِ وَهُوَ قَوْلُ أَحْمَدَ وَإِسْحَاقَ.

(1) which caused the women's pregnancies and their consequent ability to lactate. (2) This is the view held by Aḥmad and Isḥāq.
