As-Sajdah 32:3

Am yaqooloona iftarahu bal huwa alhaqqumin rabbika litunthira qawman ma atahum minnatheerin min qablika laAAallahum yahtadoon

Or do they say, "He invented it"? Rather, it is the truth from your Lord, [O Muḥammad], that you may warn a people to whom no warner has come before you [so] perhaps they will be guided.

Is it that they say, “He has fabricated it.”? No, it is the truth from your Lord, so that you (O prophet,) may warn a people to whom no warner has come before you; may be they take the right path.
