Al-Isra 17:91

قُل لَّئِنِ اجْتَمَعَتِ الْإِنسُ وَالْجِنُّ عَلَىٰ أَن يَأْتُوا بِمِثْلِ هَـٰذَا الْقُرْآنِ لَا يَأْتُونَ بِمِثْلِهِ 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."

وَلَقَدْ صَرَّفْنَا لِلنَّاسِ فِي هَـٰذَا الْقُرْآنِ مِن كُلِّ مَثَلٍ فَأَبَىٰ أَكْثَرُ النَّاسِ إِلَّا كُفُورًا

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.

وَقَالُوا لَن نُّؤْمِنَ لَكَ حَتَّىٰ تَفْجُرَ لَنَا مِنَ الْأَرْضِ يَنبُوعًا

And they say, "We will not believe you until you break open for us from the ground a spring.

أَوْ تُسْقِطَ السَّمَاءَ كَمَا زَعَمْتَ عَلَيْنَا كِسَفًا أَوْ تَأْتِيَ بِاللَّهِ وَالْمَلَائِكَةِ قَبِيلًا

Or you make the heaven fall upon us in fragments as you have claimed or you bring Allah and the angels before [us]

أَوْ يَكُونَ لَكَ بَيْتٌ مِّن زُخْرُفٍ أَوْ تَرْقَىٰ فِي السَّمَاءِ وَلَن نُّؤْمِنَ لِرُقِيِّكَ حَتَّىٰ تُنَزِّلَ عَلَيْنَا كِتَابًا نَّقْرَؤُهُ ۗ قُلْ سُبْحَانَ رَبِّي هَلْ كُنتُ إِلَّا بَشَرًا رَّسُولًا

Or you have a house of gold or you ascend into the sky. And [even then], we will not believe in your ascension until you bring down to us a book we may read." Say, "Exalted is my Lord! Was I ever but a human messenger?"

وَمَا مَنَعَ النَّاسَ أَن يُؤْمِنُوا إِذْ جَاءَهُمُ الْهُدَىٰ إِلَّا أَن قَالُوا أَبَعَثَ اللَّهُ بَشَرًا رَّسُولًا

And what prevented the people from believing when guidance came to them except that they said, "Has Allah sent a human messenger?"
