no one can produce something like it

وَلَقَدْ أَهْلَكْنَا ٱلْقُرُونَ مِن قَبْلِكُمْ لَمَّا ظَلَمُوا۟ ۙ وَجَآءَتْهُمْ رُسُلُهُم بِٱلْبَيِّنَـٰتِ وَمَا كَانُوا۟ لِيُؤْمِنُوا۟ ۚ كَذَٰلِكَ نَجْزِى ٱلْقَوْمَ ٱلْمُجْرِمِينَ

Before you people, We destroyed whole generations when they did evil- their messengers brought them clear signs but they refused to believe. This is how We repay the guilty.

ثُمَّ جَعَلْنَـٰكُمْ خَلَـٰٓئِفَ فِى ٱلْأَرْضِ مِنۢ بَعْدِهِمْ لِنَنظُرَ كَيْفَ تَعْمَلُونَ

Later We made you their successors in the land, to see how you would behave.

قُل لَّئِنِ ٱجْتَمَعَتِ ٱلْإِنسُ وَٱلْجِنُّ عَلَىٰٓ أَن يَأْتُوا۟ بِمِثْلِ هَـٰذَا ٱلْقُرْءَانِ لَا يَأْتُونَ بِمِثْلِهِۦ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا

Say, ‘Even if all mankind and jinn came together to produce something like this Quran, they could not produce anything like it, however much they helped each other.’
