It is generally held that all non-Muslims will necessarily go to Hell. Verses like the following usually form the basis of this view:

إِنَّ الَّذِينَ كَفَرُواْ مِنْ أَهْلِ الْكِتَـابِ وَالْمُشْرِكِينَ فِى نَارِ جَهَنَّمَ خَـالِدِينَ فِيهَآ أَوْلَـئِكَ هُمْ شَرُّ الْبَرِيَّةِ (98 :6)

These disbelievers among the People of the Book [Jews and Christians] and the Idolaters shall burn for ever in the fire of Hell. They are the vilest of all creatures. (98:6)[7]

It must be appreciated that these verses speak of the Jews and Christians and the Idolaters of the Prophet Muhammad’s (sws) times, who had deliberately denied the message of Muhammad (sws). As far as the non-Muslims of later times are concerned, they will meet this fate only if they are not sincere seekers of the truth and also deny the messengerhood of Muhammad (sws) in spite of being convinced about its veracity.
