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

“For, if one goes in search of a religion other than self-surrender unto God, it will never be accepted from him, and in the life to come he shall be among the lost.”

The following was revealed regarding those who apostatized and became disbelievers Whoever desires a religion other than Islam it shall not be accepted from him and in the Hereafter he shall be among the losers because he will end up in the Fire made everlasting for him.
