Messenger of Allah ﷺ 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."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَمُوتُ لأَحَدٍ مِنَ الْمُسْلِمِينَ ثَلاَثَةٌ مِنَ الْوَلَدِ تَمَسُّهُ النَّارُ إِلاَّ تَحِلَّةَ الْقَسَمِ
