Quran 26:190 — The Poets (Al-Shu`ara')

This should be a lesson, but most people are not believers.

[26:189] They disbelieved him and, consequently, they incurred the retribution of the Day of the Canopy. It was the retribution of an awesome day.

[26:191] Most assuredly, your Lord is the Almighty, Most Merciful.
