The Prophet ﷺ made a man and his wife carry out Lian, and the husband repudiated her child. So the Prophet got them separated (by divorce) and decided that the child belonged to the mother only.  

أَنَّ النَّبِيَّ ﷺ لاَعَنَ بَيْنَ رَجُلٍ وَامْرَأَتِهِ فَانْتَفَى مِنْ وَلَدِهَا فَفَرَّقَ بَيْنَهُمَا وَأَلْحَقَ الْوَلَدَ بِالْمَرْأَةِ
