Your opinion is incorrect.
God says in the Quran.
Surah Aal-e-Imran, Ayat 85
وَمَن يَبْتَغِ غَيْرَ الْإِسْلَامِ دِينًا فَلَن يُقْبَلَ مِنْهُ وَهُوَ فِي الْآخِرَةِ مِنَ الْخَاسِرِينَ
And whoever desires a religion other than Islam, it shall not be accepted from him, and in the hereafter he shall be one of the losers.
Surah Aal-e-Imran, Ayat 91
إِنَّ الَّذِينَ كَفَرُوا وَمَاتُوا وَهُمْ كُفَّارٌ فَلَن يُقْبَلَ مِنْ أَحَدِهِم مِّلْءُ الْأَرْضِ ذَهَبًا وَلَوِ افْتَدَىٰ بِهِ ۗ أُولَـٰئِكَ لَهُمْ عَذَابٌ أَلِيمٌ وَمَا لَهُم مِّن نَّاصِرِينَ
Surely, those who disbelieve and die while they are unbelievers, the earth full of gold shall not be accepted from one of them, though he should offer to ransom himself with it, these it is who shall have a painful chastisement, and they shall have no helpers.
