The Holy Quran 86:14 — Surah At-Tariq
Arabic text
وَمَا هُوَ بِٱلْهَزْلِ
Translation
...and it is no joke (it should not be treated lightly).
Tafsir (excerpt) — Tafsir Usmani
The Quran is a decisive word: that is, the Quran, and all it states concerning ma'ad (the return to Allah after death), is no matter for jest and joking. Rather, it is a decisive judgement between truth and falsehood, between truthfulness and lying. Without doubt it is the true Word and gives news of a settled matter which will certainly come to pass.
