ALI 'IMRAN — Ayat 19

إِنَّ الدِّينَ عِندَ اللّهِ الإِسْلاَمُ وَمَا اخْتَلَفَ الَّذِينَ أُوْتُواْ الْكِتَابَ إِلاَّ مِن بَعْدِ مَا جَاءهُمُ الْعِلْمُ بَغْيًا بَيْنَهُمْ وَمَن يَكْفُرْ بِآيَاتِ اللّهِ فَإِنَّ اللّهِ سَرِيعُ الْحِسَابِ

Indeed, the religion in the sight of Allah is Islam. And those who were given the Scripture did not differ except after knowledge had come to them - out of jealous animosity between themselves. And whoever disbelieves in the verses of Allah , then indeed, Allah is swift in [taking] account.
