Al Isra, 88 Ayah
17:88
قُل لَّئِنِ ٱجۡتَمَعَتِ ٱلۡإِنسُ وَٱلۡجِنُّ عَلَىٰٓ أَن يَأۡتُواْ بِمِثۡلِ هَٰذَا ٱلۡقُرۡءَانِ لَا يَأۡتُونَ بِمِثۡلِهِۦ وَلَوۡ كَانَ بَعۡضُهُمۡ لِبَعۡضٖ ظَهِيرٗا ٨٨
Qul La'ini Ajtama`ati Al-'Insu Wa Al-Jinnu `Alá 'An Ya'tū Bimithli Hādhā Al-Qur'āni Lā Ya'tūna Bimithlihi Wa Law Kāna Ba`đuhum Liba`đin Žahīrāan
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."
