Surat Ali ‘Imran Ayat 19
إِنَّ ٱلدِّينَ عِندَ ٱللَّهِ ٱلْإِسْلَٰمُ ۗ وَمَا ٱخْتَلَفَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ إِلَّا مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْعِلْمُ بَغْيًۢا بَيْنَهُمْ ۗ وَمَن يَكْفُرْ بِـَٔايَٰتِ ٱللَّهِ فَإِنَّ ٱللَّهَ سَرِيعُ ٱلْحِسَابِ

Meaning: Indeed, the religion (that is acceptable) in the sight of Allah is only Islam. There is no dispute between those who have been given the Book except after knowledge has come to them, because of envy (which exists) between them. Whoever disbelieves in the verses of Allah, Allah is very quick in reckoning.
