Sahih al-Bukhari, Hadith 5315 ⓘ
Narrated Ibn `Umar: The Prophet 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.
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا مَالِكٌ، قَالَ حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم لاَعَنَ بَيْنَ رَجُلٍ وَامْرَأَتِهِ، فَانْتَفَى مِنْ وَلَدِهَا فَفَرَّقَ بَيْنَهُمَا، وَأَلْحَقَ الْوَلَدَ بِالْمَرْأَةِ.
