Surah As-Sajdah, Verse 3

أَمۡ يَقُولُونَ ٱفۡتَرَىٰهُۚ بَلۡ هُوَ ٱلۡحَقُّ مِن رَّبِّكَ لِتُنذِرَ قَوۡمٗا مَّآ أَتَىٰهُم مِّن نَّذِيرٖ مِّن قَبۡلِكَ لَعَلَّهُمۡ يَهۡتَدُونَ٣

am yaqūlūna if'tarāhu bal huwa l-ḥaqu min rabbika litundhira qawman mā atāhum min nadhīrin min qablika laʿallahum yahtadūna

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.
