الاسراۤء — Al-Isra' Ayat 88
قُلْ لَّىِٕنِ اجْتَمَعَتِ الْاِنْسُ وَالْجِنُّ عَلٰٓى اَنْ يَّأْتُوْا بِمِثْلِ هٰذَا الْقُرْاٰنِ لَا يَأْتُوْنَ بِمِثْلِهٖ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيْرًا
Qul la'inijtama‘atil-insu wal-jinnu ‘alā ay ya'tū bimiṡli hāżal-qur'āni lā ya'tūna bimiṡlihī wa lau kāna ba‘ḍuhum liba‘ḍin ẓahīrā(n).
"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.""
