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
[3:19]
Surely the (true) religion with Allah is Islam, and those to whom the Book had been given did not show opposition but after knowledge had come to them, out of envy among themselves; and whoever disbelieves in the communications of Allah then surely Allah is quick in reckoning.
The Religion before Allah is Islam (submission to His Will): Nor did the People of the Book dissent therefrom except through envy of each other, after knowledge had come to them. But if any deny the Signs of Allah, Allah is swift in calling to account.
Lo! religion with Allah (is) the Surrender (to His Will and Guidance). Those who (formerly) received the Scripture differed only after knowledge came unto them, through transgression among themselves. Whoso disbelieveth the revelations of Allah (will find that) lo! Allah is swift at reckoning.
