Al-Anbya 108

قُلْ إِنَّمَا يُوحَىٰٓ إِلَىَّ أَنَّمَآ إِلَـٰهُكُمْ إِلَـٰهٌ وَٰحِدٌ ۖ فَهَلْ أَنتُم مُّسْلِمُونَ

qul innamā yūḥā ilayya annamā ilāhukum ilāhun wāḥidun fahal antum mus'limūna

Say, "It is only revealed to me that your god is but one God; so will you be Muslims [in submission to Him]?"
