Quran 34:31 from Surah Saba on Divine Marvels.
وَقَالَ ٱلَّذِينَ كَفَرُواْ لَن نُّؤۡمِنَ بِهَٰذَا ٱلۡقُرۡءَانِ وَلَا بِٱلَّذِي بَيۡنَ يَدَيۡهِۗ وَلَوۡ تَرَىٰٓ إِذِ ٱلظَّٰلِمُونَ مَوۡقُوفُونَ عِندَ رَبِّهِمۡ يَرۡجِعُ بَعۡضُهُمۡ إِلَىٰ بَعۡضٍ ٱلۡقَوۡلَ يَقُولُ ٱلَّذِينَ ٱسۡتُضۡعِفُواْ لِلَّذِينَ ٱسۡتَكۡبَرُواْ لَوۡلَآ أَنتُمۡ لَكُنَّا مُؤۡمِنِينَ
English translation: And say those who disbelieve Never will we believe in this Quran and not in (that) which (was) before it (was) before it But if you (could) see when the wrongdoers will be made to stand before their Lord will throw back some of them to others the word Will say those who were oppressed to those who were arrogant If not (for) you certainly we (would) have been believers
