سُورَةُ الإِسۡرَاءِ
Al-Israa·17:88
قُلْ لَئِنِ اجْتَمَعَتِ الْإِنْسُ وَالْجِنُّ عَلَىٰ أَنْ يَأْتُوا بِمِثْلِ هَٰذَا الْقُرْآنِ لَا يَأْتُونَ بِمِثْلِهِ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا٨٨
Say: "If all mankind and all invisible beings would come together with a view to producing the like of this Qur'an, they could not produce its like even though they were to exert all their strength in aiding one another!"
