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." (Using translation from Bukhārī 6656)

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «لَا يَمُوتُ لِأَحَدٍ مِنَ الْمُسْلِمِينَ ثَلَاثَةٌ مِنَ الْوَلَدِ فَتَمَسَّهُ النَّارُ إِلَّا تَحِلَّةِ الْقَسَمِ»
