It is narrated on the authority of Abu Huraira that the Messenger of Allah ﷺ observed: By Him in Whose hand is the life of Muhammad, he who amongst the community of Jews or Christians hears about me, but does not affirm his belief in that with which I have been sent and dies in this state (of disbelief), he shall be but one of the denizens of Hell-Fire.

حَدَّثَنِي يُونُسُ بْنُ عَبْدِ الأَعْلَى، أَخْبَرَنَا ابْنُ وَهْبٍ، قَالَ وَأَخْبَرَنِي عَمْرٌو، أَنَّ أَبَا يُونُسَ، حَدَّثَهُ عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ " وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لاَ يَسْمَعُ بِي أَحَدٌ مِنْ هَذِهِ الأُمَّةِ يَهُودِيٌّ وَلاَ نَصْرَانِيٌّ ثُمَّ يَمُوتُ وَلَمْ يُؤْمِنْ بِالَّذِي أُرْسِلْتُ بِهِ إِلاَّ كَانَ مِنْ أَصْحَابِ النَّارِ " .
