Nafi' reported on the authority of Ibn Umar (Allah be pleased with them) that a person invoked curse on the wife during the lifetime of Allah s Messenger ﷺ, so he effected separation between them and traced the lineage of the son to his mother.

وَحَدَّثَنَا سَعِيدُ بْنُ مَنْصُورٍ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا مَالِكٌ، ح وَحَدَّثَنَا يَحْيَى، بْنُ يَحْيَى - وَاللَّفْظُ لَهُ - قَالَ قُلْتُ لِمَالِكٍ حَدَّثَكَ نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ رَجُلاً، لاَعَنَ امْرَأَتَهُ عَلَى عَهْدِ رَسُولِ اللَّهِ ﷺ فَفَرَّقَ رَسُولُ اللَّهِ ﷺ بَيْنَهُمَا وَأَلْحَقَ الْوَلَدَ بِأُمِّهِ قَالَ نَعَمْ .
