The Insight
Surah Al-Masad was revealed while Abu Lahab, the Prophet's own uncle and one of his fiercest opponents, was still alive. It does not call him a sinner in general terms. It names him specifically and declares his end sealed. This is extraordinary because the falsification mechanism was right there: Abu Lahab could have walked up to the Prophet, recited the shahada, and the prophecy would have been broken. No elaborate counter-argument needed, just two words. He had years. He never converted. He died in 624 CE, days after the Battle of Badr, still an enemy of the faith whose rise he had devoted his life to preventing. The surah named a specific living person, staked the Quran's credibility on his future behaviour, and was never disproved.
