2:137
فَإِنْ ءَامَنُوا۟ بِمِثْلِ مَآ ءَامَنتُم بِهِۦ فَقَدِ ٱهْتَدَوا۟ ۖ وَّإِن تَوَلَّوْا۟ فَإِنَّمَا هُمْ فِى شِقَاقٍ ۖ فَسَيَكْفِيكَهُمُ ٱللَّهُ ۚ وَهُوَ ٱلسَّمِيعُ ٱلْعَلِيمُ١٣٧
So if they believe in the same as you believe in, then they have been [rightly] guided; but if they turn away, they are only in dissension, and Allāh will be sufficient for you against them. And He is the Hearing, the Knowing.
