Sura Sabaʾ 34:28

وَمَآ أَرْسَلْنَٰكَ إِلَّا كَآفَّةً لِّلنَّاسِ بَشِيرًا وَنَذِيرًا وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ

wa-mā arsalnāka illā kāffatan lil-nāsi bashīran wa-nadhīran wa-lākinna akthara l-nāsi lā yaʿlamūna

We have not sent thee but as a universal (Messenger) to men, giving them glad tidings, and warning them (against sin), but most men understand not.
