Islam is the only way

حَدَّثَنِي يُونُسُ بْنُ عَبْدِ الْأَعْلَی أَخْبَرَنَا ابْنُ وَهْبٍ قَالَ وَأَخْبَرَنِي عَمْرٌو أَنَّ أَبَا يُونُسَ حَدَّثَهُ عَنْ أَبِي هُرَيْرَةَ عَنْ رَسُولِ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ وَالَّذِي نَفْسُ مُحَمَّدٍ بِيَدِهِ لَا يَسْمَعُ بِي أَحَدٌ مِنْ هَذِهِ الْأُمَّةِ يَهُودِيٌّ وَلَا نَصْرَانِيٌّ ثُمَّ يَمُوتُ وَلَمْ يُؤْمِنْ بِالَّذِي أُرْسِلْتُ بِهِ إِلَّا کَانَ مِنْ أَصْحَابِ النَّارِ

It is narrated on the authority of Abu Hurairahرضی اللہ عنہ that the Messenger of Allahﷺ 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.
