And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.
The Saheeh International Quran Translation
وَمَن يَبْتَغِ غَيْرَ ٱلْإِسْلَٰمِ دِينًا فَلَن يُقْبَلَ مِنْهُ وَهُوَ فِى ٱلْءَاخِرَةِ مِنَ ٱلْخَٰسِرِينَAnd whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.
