فَإِنْ So if ءَامَنُوا۟ they believe[d] بِمِثْلِ in (the) like مَآ (of) what ءَامَنتُم you have believed بِهِۦ in [it] فَقَدِ then indeed ٱهْتَدَوا۟ ۖ they are (rightly) guided وَّإِن But if تَوَلَّوْا۟ they turn away فَإِنَّمَا then only هُمْ they فِى (are) in شِقَاقٍۢ ۖ dissension فَسَيَكْفِيكَهُمُ So will suffice you against them ٱللَّهُ ۚ Allah وَهُوَ and He ٱلسَّمِيعُ (is) the All-Hearing ٱلْعَلِيمُ the All-Knowing ١٣٧
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.
