Narrated Abu Huraira: Allah's Messenger said, "Any Muslim who has lost three of his children will not be touched by the Fire except that which will render Allah's oath fulfilled."
حَدَّثَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنِ ابْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَمُوتُ لأَحَدٍ مِنَ الْمُسْلِمِينَ ثَلاَثَةٌ مِنَ الْوَلَدِ، تَمَسُّهُ النَّارُ، إِلاَّ تَحِلَّةَ الْقَسَمِ " .
