Quran 11:14 from Surah Hud on Divine Marvels.
فَإِلَّمۡ يَسۡتَجِيبُواْ لَكُمۡ فَٱعۡلَمُوٓاْ أَنَّمَآ أُنزِلَ بِعِلۡمِ ٱللَّهِ وَأَن لَّآ إِلَٰهَ إِلَّا هُوَۖ فَهَلۡ أَنتُم مُّسۡلِمُونَ
English translation: Then if not they respond to you then know that it was sent down with the knowledge of Allah and that (there is) no god except Him Then, would you (be) Muslims
Transliteration: fa-illam yastajibu lakum fa-i'lamu annama unzila bi'il'mi al-lahi wa-an la ilaha illa huwa fahal antum mus'limuna
