Aal-i-Imraan 85

وَمَن يَبْتَغِ غَيْرَ ٱلْإِسْلَٰمِ دِينًا فَلَن يُقْبَلَ مِنْهُ وَهُوَ فِى ٱلْءَاخِرَةِ مِنَ ٱلْخَٰسِرِينَ ﴿٨٥﴾

Waman yabtaghi ghayra alislami deenan falan yuqbala minhu wahuwa fee alakhirati mina alkhasireena

And whoever seeks a religion other than Islam, it will never be accepted of him, and in the Hereafter he will be one of the losers. The Noble Quran
