Quran 3:20 from Surah Aal-i-Imraan on Divine Marvels.
فَإِنۡ حَآجُّوكَ فَقُلۡ أَسۡلَمۡتُ وَجۡهِيَ لِلَّهِ وَمَنِ ٱتَّبَعَنِۗ وَقُل لِّلَّذِينَ أُوتُواْ ٱلۡكِتَٰبَ وَٱلۡأُمِّيِّـۧنَ ءَأَسۡلَمۡتُمۡۚ فَإِنۡ أَسۡلَمُواْ فَقَدِ ٱهۡتَدَواْۖ وَّإِن تَوَلَّوۡاْ فَإِنَّمَا عَلَيۡكَ ٱلۡبَلَٰغُۗ وَٱللَّهُ بَصِيرُۢ بِٱلۡعِبَادِ
English translation: Then if they argue with you then say I have submitted myself to Allah and (those) who follow me And say to those who were given the Book and the unlettered people Have you submitted yourselves Then if they submit then surely they are guided But if they turn back then only on you (is) to [the] convey And Allah (is) All-Seer of [His] slaves
