As-Saffat 37:12

دُحُورًا ۖ وَلَهُمْ عَذَابٌ وَاصِبٌ

Repelled; and for them is a constant punishment,

إِلَّا مَنْ خَطِفَ الْخَطْفَةَ فَأَتْبَعَهُ شِهَابٌ ثَاقِبٌ

Except one who snatches [some words] by theft, but they are pursued by a burning flame, piercing [in brightness].

فَاسْتَفْتِهِمْ أَهُمْ أَشَدُّ خَلْقًا أَم مَّنْ خَلَقْنَا ۚ إِنَّا خَلَقْنَاهُم مِّن طِينٍ لَّازِبٍ

Then inquire of them, [O Muhammad], "Are they a stronger [or more difficult] creation or those [others] We have created?" Indeed, We created men from sticky clay.

وَإِذَا ذُكِّرُوا لَا يَذْكُرُونَ

And when they are reminded, they remember not.

وَإِذَا رَأَوْا آيَةً يَسْتَسْخِرُونَ

And when they see a sign, they ridicule

وَقَالُوا إِنْ هَـٰذَا إِلَّا سِحْرٌ مُّبِينٌ

And say, "This is not but obvious magic.
