فَإِنۡ ءَامَنُواْ بِمِثۡلِ مَآ ءَامَنتُم بِهِۦ فَقَدِ ٱهۡتَدَواْۖ وَّإِن تَوَلَّوۡاْ فَإِنَّمَا هُمۡ فِي شِقَاقٖۖ فَسَيَكۡفِيكَهُمُ ٱللَّهُۚ وَهُوَ ٱلسَّمِيعُ ٱلۡعَلِيمُ 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.
Translation: Saheeh International (English)
Each word's meaning and sound
If the Jews and the Christians, and other disbelievers, have faith in the same way that you do, then they have been guided to the right way of life which Allah is satisfied with. Yet if they turn away from faith because they reject all the prophets or some of them, then they are in disagreement and are against you. Do not be sad, O Prophet, because Allah will protect you from their harm and evil, and give you victory over them. Allah hears all that they say, and knows all their intentions and actions.
