Al-Isra 17:89

وَلَئِن شِئْنَا لَنَذْهَبَنَّ بِالَّذِي أَوْحَيْنَا إِلَيْكَ ثُمَّ لَا تَجِدُ لَكَ بِهِ عَلَيْنَا وَكِيلًا

And if We willed, We could surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against Us.

إِلَّا رَحْمَةً مِّن رَّبِّكَ ۚ إِنَّ فَضْلَهُ كَانَ عَلَيْكَ كَبِيرًا

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

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."

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 تَكُونَ لَكَ جَنَّةٌ مِّن نَّخِيلٍ وَعِنَبٍ فَتُفَجِّرَ الْأَنْهَارَ خِلَالَهَا تَفْجِيرًا

Or [until] you have a garden of palm tress and grapes and make rivers gush forth within them in force [and abundance]

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]
