Surah Al-Qamar, verse 23

فَكَيْفَ كَانَ عَذَابِى وَنُذُرِ ﴿٢١﴾

And how [severe] were My punishment and warning.

وَلَقَدْ يَسَّرْنَا ٱلْقُرْءَانَ لِلذِّكْرِ فَهَلْ مِن مُّدَّكِرٍۢ ﴿٢٢﴾

And We have certainly made the Qur’ān easy for remembrance, so is there any who will remember?

فَقَالُوٓا۟ أَبَشَرًۭا مِّنَّا وَٰحِدًۭا نَّتَّبِعُهُۥٓ إِنَّآ إِذًۭا لَّفِى ضَلَـٰلٍۢ وَسُعُرٍ ﴿٢٤﴾

And said, "Is it one human being among us that we should follow? Indeed, we would then be in error and madness.

أَءُلْقِىَ ٱلذِّكْرُ عَلَيْهِ مِنۢ بَيْنِنَا بَلْ هُوَ كَذَّابٌ أَشِرٌۭ ﴿٢٥﴾

Has the message been sent down upon him from among us? Rather, he is an insolent liar."
