Surah Al-Anbya — Ayah 7 (21:7)
وَمَآ أَرۡسَلۡنَا قَبۡلَكَ إِلَّا رِجَالٗا نُّوحِيٓ إِلَيۡهِمۡۖ فَسۡـَٔلُوٓاْ أَهۡلَ ٱلذِّكۡرِ إِن كُنتُمۡ لَا تَعۡلَمُونَ ٧
English translation (Saheeh International)
And We sent not before you, [O Muḥammad], except men to whom We revealed [the message], so ask the people of the message [i.e., former scriptures] if you do not know.
Brief commentary
And I did not send before you, O Messenger, except men amongst humans to whom I would send revelation. I did not send them as angels, so ask the People of the Book before you if you do not know this.
