Invoking Curses - Section 1
وَعَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَاعن بَين رجل وَامْرَأَته فانتقى مِنْ وَلَدِهَا فَفَرَّقَ بَيْنَهُمَا وَأَلْحَقَ الْوَلَدَ بِالْمَرْأَةِ. مُتَّفَقٌ عَلَيْهِ. وَفِي حَدِيثِهِ لَهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَعَظَهُ وَذَكَّرَهُ وَأَخْبَرَهُ أَنَّ عَذَابَ الدُّنْيَا أَهْوَنُ مِنْ عَذَابِ الْآخِرَةِ ثُمَّ دَعَاهَا فَوَعَظَهَا وَذَكَّرَهَا وَأَخْبَرَهَا أَنَّ عَذَاب الدُّنْيَا أَهْون من عَذَاب الْآخِرَة
Ibn ‘Umar said that the Prophet (ﷺ) made a man and his wife invoke curses when the man disowned her child, and separated them and attributed the child to the woman. In his tradition transmitted by both of them it says that God's Messenger exhorted and admonished the man and informed him that punishment in this world is easier than that in the next. He then summoned the woman and exhorted and admonished her and told her that punishment in this world is easier than that in the next. (Bukhari and Muslim.)
