فَإِلَّمْ يَسْتَجِيبُوا۟ لَكُمْ فَٱعْلَمُوٓا۟ أَنَّمَآ أُنزِلَ بِعِلْمِ ٱللَّهِ وَأَن لَّآ إِلَـٰهَ إِلَّا هُوَ ۖ فَهَلْ أَنتُم مُّسْلِمُونَ١٤
And if they do not respond to you - then know that it [i.e., the Qur’ān] was revealed with the knowledge of Allāh1 and that there is no deity except Him. Then,2 would you [not] be Muslims?
