فَإِلَّمۡ يَسۡتَجِيبُواْ لَكُمۡ فَٱعۡلَمُوٓاْ أَنَّمَآ أُنزِلَ بِعِلۡمِ ٱللَّهِ وَأَن لَّآ إِلَٰهَ إِلَّا هُوَۖ فَهَلۡ أَنتُم مُّسۡلِمُونَ
Fa il lam yastajeeboo lakum fa'lamooo annamaaa unzilla bi'ilmil laahi wa al laaa ilaaha illaa Huwa fahal antum muslimoon
English Translation
And if they do not respond to you - then know that the Qur'an was revealed with the knowledge of Allah and that there is no deity except Him. Then, would you [not] be Muslims
