Ibn ‘Umar said A man invoked curses on his wife (charging her of adultery) during the time of Apostle of Allaahﷺ and disowned the child. The Apostle of Allaahﷺ therefore separated them and attributed the child to the woman.
Abu Dawud said “The words narrated by Malik alone are “and he attributed the child to the woman.”"

Abu Dawud said:

The words narrated by Malik alone are: "and he attributed the child to the woman."

Yunus narrated from Al Zuhri on the authority of Sahl bin Sa’d in the tradition regarding li’an(invoking curses). He disowned her conception hence her child was attributed to her.

حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَجُلاً، لاَعَنَ امْرَأَتَهُ فِي زَمَانِ رَسُولِ اللَّهِ ﷺ وَانْتَفَى مِنْ وَلَدِهَا فَفَرَّقَ رَسُولُ اللَّهِ ﷺ بَيْنَهُمَا وَأَلْحَقَ الْوَلَدَ بِالْمَرْأَةِ . قَالَ أَبُو دَاوُدَ الَّذِي تَفَرَّدَ بِهِ مَالِكٌ قَوْلُهُ
" وَأَلْحَقَ الْوَلَدَ بِالْمَرْأَةِ " . وَقَالَ يُونُسُ عَنِ الزُّهْرِيِّ عَنْ سَهْلِ بْنِ سَعْدٍ فِي حَدِيثِ اللِّعَانِ وَأَنْكَرَ حَمْلَهَا فَكَانَ ابْنُهَا يُدْعَى إِلَيْهَا .
