Surah 32:3
"Or do they say, ‘He has forged it’? No! It is the truth from your Lord, so that you may warn a people to whom no warner has come before you, so that they may be (rightly) guided."
32.3 – Or do they say, “He has forged it”?
In spite of verse 2, many listeners doubt both the message and the messenger. The objection, “He has forged it,” appears at least seventeen times in the Quran. This verse asserts the truth of the message and claims the necessity of the messenger. See the discussion on verses that accuse the messenger of inventing at 69.44.
