فَإِنْ So if fa-in they believe[d] āmanū in (the) like bimith'li (of) what mā you have believed āmantum in [it] bihi then indeed faqadi they are (rightly) guided ih'tadaw But if wa-in they turn away tawallaw then only fa-innamā they hum (are) in fī dissension shiqāqin So will suffice you against them fasayakfīkahumu Allah l-lahu and He wahuwa (is) the All-Hearing l-samīʿu the All-Knowing l-ʿalīmu
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.
