Quran 21:7 from Surah Al-Anbiyaa on Divine Marvels.
وَمَآ أَرۡسَلۡنَا قَبۡلَكَ إِلَّا رِجَالٗا نُّوحِيٓ إِلَيۡهِمۡۖ فَسۡـَٔلُوٓاْ أَهۡلَ ٱلذِّكۡرِ إِن كُنتُمۡ لَا تَعۡلَمُونَ
English translation: And not We sent before you except men We revealed to them So ask (the) people (of) the Reminder if you (do) not know
Transliteration: wama arsalna qablaka illa rijalan nuhi ilayhim fasalu ahla al-dhik'ri in kuntum la ta'lamuna
