اٰل عمران — Ali 'Imran Ayat 19
اِنَّ الدِّيْنَ عِنْدَ اللّٰهِ الْاِسْلَامُ ۗ وَمَا اخْتَلَفَ الَّذِيْنَ اُوْتُوا الْكِتٰبَ اِلَّا مِنْۢ بَعْدِ مَا جَاۤءَهُمُ الْعِلْمُ بَغْيًاۢ بَيْنَهُمْ ۗوَمَنْ يَّكْفُرْ بِاٰيٰتِ اللّٰهِ فَاِنَّ اللّٰهَ سَرِيْعُ الْحِسَابِ
Innad-dīna ‘indallāhil-islām(u), wa makhtalafal-lażīna ūtul-kitāba illā mim ba‘di mā jā'ahumul-‘ilmu bagyam bainahum, wa may yakfur bi'āyātillāhi fa innallāha sarī‘ul-ḥisāb(i).
"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."
