No Muslim would die but Allah would admit in his stead a Jew or a Christian in Hell-Fire. 'Umar b. Abd al-'Aziz took an oath: By One besides Whom there is no god but He, thrice that his father had narrated that to him from Messenger of Allah ﷺ. (Using translation from Muslim 2767b)
عَنِ النَّبِيِّ ﷺ قَالَ لَا يَمُوتُ رَجُلٌ مُسْلِمٌ إِلَّاأَدْخَلَ اللهُ ﷻ مَكَانَهُ النَّارَ يَهُودِيًّا أَوْ نَصْرَانِيًّا قَالَ فَاسْتَحْلَفَهُ عُمَرُ بْنُ عَبْدِ الْعَزِيزِ بِاللهِ الَّذِي لَا إِلَهَ إِلَّا هُوَ ثَلَاثَ مَرَّاتٍ أَنَّ أَبَاهُ حَدَّثَهُ عَنْ رَسُولِ اللهِ ﷺ قَالَ فَحَلَفَ لَهُ قَالَ فَلَمْ يُحَدِّثْنِي سَعِيدٌ أَنَّهُ اسْتَحْلَفَهُ وَلَمْ يُنْكِرْ عَلَى عَوْنٍ قَوْلَهُ
