Surah As-Sajdah 32:3

أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۚ بَلْ هُوَ ٱلْحَقُّ مِن رَّبِّكَ لِتُنذِرَ قَوْمًا مَّآ أَتَىٰهُم مِّن نَّذِيرٍ مِّن قَبْلِكَ لَعَلَّهُمْ يَهْتَدُونَ

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.

Translation: Saheeh International

Tafsir

Or do they say ‘He Muhammad (s) has invented it’? Nay but it is the truth from your Lord that you may warn thereby a people to whom no warner came before you mā is for negation that perhaps they may find right guidance by your warning.
