(Isra) 17 : 88
قُلْ لَئِنِ اجْتَمَعَتِ الْإِنْسُ وَالْجِنُّ عَلَىٰ أَنْ يَأْتُوا بِمِثْلِ هَٰذَا الْقُرْآنِ لَا يَأْتُونَ بِمِثْلِهِ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا
You say: "If mankind and the Jinn gathered to produce a Reading like This, they could not produce one similar to It, even if they assist one another”.
See explanation 2: 23-24; 11: 13-14 and 17.
