وَ مَعْنَاهُ أَنَّهُ إِذَا أُرْضِعَ الصَّبِيُّ حَوْلَيْنِ كَامِلَيْنِ ثُمَّ شَرِبَ بَعْدَ ذَلِكَ مِنْ لَبَنِ امْرَأَةٍ أُخْرَى مَا شَرِبَ لَمْ يُحَرِّمْ ذَلِكَ الرَّضَاعُ لِأَنَّهُ رَضَاعٌ بَعْدَ فِطَامٍ.
Its meaning is that if a child has been breastfed for two full years and then drinks milk from another woman after that, such breastfeeding does not establish a prohibition, because it is breastfeeding after weaning.
