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

Say, "If mankind and the jinn gathered in order to produce the like of this Qur'an, they could not produce the like of it, even if they were to each other assistants."
