قُل لَّئِنِ اجْتَمَعَتِ الإِنسُ وَالْجِنُّ عَلَى أَن يَأْتُواْ بِمِثْلِ هَذَا الْقُرْآنِ لاَ يَأْتُونَ بِمِثْلِهِ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا
﴿٨٨﴾
سورة الإسراء
(17/88) Say thou: if the mankind and the jinn leagued together that they might produce the like of this Qur´an, they could nor produce the like thereof, though one to the other were a backer.
Surah Al-Isra
