فَإِنْ آمَنُواْ بِمِثْلِ مَا آمَنتُم بِهِ فَقَدِ اهْتَدَواْ وَّإِن تَوَلَّوْاْ فَإِنَّمَا هُمْ فِي شِقَاقٍ فَسَيَكْفِيكَهُمُ اللّهُ وَهُوَ السَّمِيعُ الْعَلِيمُ
[2:137]
If then they believe as you believe in Him, they are indeed on the right course, and if they turn back, then they are only in great opposition, so Allah will suffice you against them, and He is the Hearing, the Knowing.
So if they believe as ye believe, they are indeed on the right path; but if they turn back, it is they who are in schism; but Allah will suffice thee as against them, and He is the All-Hearing, the All-Knowing.
And if they believe in the like of that which ye believe, then are they rightly guided. But if they turn away, then are they in schism, and Allah will suffice thee (for defence) against them. He is the Hearer, the Knower.
