Surah Aal-e-Imranوَمَن يَبۡتَغِ غَيۡرَ ٱلۡإِسۡلَٰمِ دِينٗا فَلَن يُقۡبَلَ مِنۡهُ وَهُوَ فِي ٱلۡأٓخِرَةِ مِنَ ٱلۡخَٰسِرِينَ
Whoever seeks as religion other than Islam, it will not be accepted from him, and he will be a loser in the Hereafter. (This is because the religion, DEEN of the entire Universe is Islam i.e. submission to the will of God)
