Quran 17:88 — The Children of Israel (Bani Israel)

قُل لَئِنِ اجتَمَعَتِ الإِنسُ وَالجِنُّ عَلىٰ أَن يَأتوا بِمِثلِ هٰذَا القُرءانِ لا يَأتونَ بِمِثلِهِ وَلَو كانَ بَعضُهُم لِبَعضٍ ظَهيرًا

Say, "If all the humans and all the jinns banded together in order to produce a Quran like this, they could never produce anything like it, no matter how much assistance they lent one another."

[17:87] This is but mercy from your Lord. His blessings upon you have been great.

[17:89] We have cited for the people in this Quran all kinds of examples, but most people insist upon disbelieving.
