At-Tur 52:33

أَمْ يَقُولُونَ شَاعِرٌ نَّتَرَبَّصُ بِهِ رَيْبَ الْمَنُونِ

Or do they say [of you], "A poet for whom we await a misfortune of time?"

قُلْ تَرَبَّصُوا فَإِنِّي مَعَكُم مِّنَ الْمُتَرَبِّصِينَ

Say, "Wait, for indeed I am, with you, among the waiters."

أَمْ تَأْمُرُهُمْ أَحْلَامُهُم بِهَـٰذَا ۚ أَمْ هُمْ قَوْمٌ طَاغُونَ

Or do their minds command them to [say] this, or are they a transgressing people?

فَلْيَأْتُوا بِحَدِيثٍ مِّثْلِهِ إِن كَانُوا صَادِقِينَ

Then let them produce a statement like it, if they should be truthful.

أَمْ خُلِقُوا مِنْ غَيْرِ شَيْءٍ أَمْ هُمُ الْخَالِقُونَ

Or were they created by nothing, or were they the creators [of themselves]?

أَمْ خَلَقُوا السَّمَاوَاتِ وَالْأَرْضَ ۚ بَل لَّا يُوقِنُونَ

Or did they create the heavens and the earth? Rather, they are not certain.
