Verse 14

فَإِلَّمْ يَسْتَجِيبُوا۟ لَكُمْ فَٱعْلَمُوٓا۟ أَنَّمَآ أُنزِلَ بِعِلْمِ ٱللَّهِ وَأَن لَّآ إِلَـٰهَ إِلَّا هُوَ فَهَلْ أَنتُم مُّسْلِمُونَ

And if they cannot respond to you, then you shall know that indeed it was revealed with God’s knowledge and there is no god except He.  Therefore, would you become peace offerors?
