The Night Journey
قُل لَّئِنِ ٱجْتَمَعَتِ ٱلْإِنسُ وَٱلْجِنُّ عَلَىٰٓ أَن يَأْتُوا۟ بِمِثْلِ هَـٰذَا ٱلْقُرْءَانِ لَا يَأْتُونَ بِمِثْلِهِۦ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا
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."
Nearby ayahs help place verse 17:88 in sequence and meaning.
وَلَئِن شِئْنَا لَنَذْهَبَنَّ بِٱلَّذِىٓ أَوْحَيْنَآ إِلَيْكَ ثُمَّ لَا تَجِدُ لَكَ بِهِۦ عَلَيْنَا وَكِيلًا

Except [We have left it with you] as a mercy from your Lord. Indeed, His favor upon you has ever been great.

And We have certainly diversified for the people in this Qur'an from every [kind] of example, but most of the people refused [anything] except disbelief.
وَقَالُوا۟ لَن نُّؤْمِنَ لَكَ حَتَّىٰ تَفْجُرَ لَنَا مِنَ ٱلْأَرْضِ يَنۢبُوعًا
And they say, "We will not believe you until you break open for us from the ground a spring.
