Surah 74. Al-Muddaththir, Ayah 49

I.e., with so many people who refuse to listen to the truth.

If the Day of Judgment is inevitable, it is strange that men should not heed a plain warning, but go on as if they were thoughtless and obstinate asses stampeding from a lion. Instead of heeding the warning, they try to avoid it. They are frightened at Allah's Word.
