Aal-i-Imraan 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 ﴿١٩﴾

Inna alddeena AAinda Allahi alislamu wama ikhtalafa allatheena ootoo alkitaba illa min baAAdi ma jaahumu alAAilmu baghyan baynahum waman yakfur biayati Allahi fainna Allaha sareeAAu alhisabi

And whoever disbelieves in the Ayat (proofs, evidences, verses, signs, revelations, etc.) of Allah, then surely, Allah is Swift in calling to account. The Noble Quran
