Surah As-Sajda, Verse 3
أَمْ يَقُولُونَ ٱفْتَرَىٰهُ ۚ بَلْ هُوَ ٱلْحَقُّ مِن رَّبِّكَ لِتُنذِرَ قَوْمًۭا مَّآ أَتَىٰهُم مِّن نَّذِيرٍۢ مِّن قَبْلِكَ لَعَلَّهُمْ يَهْتَدُونَ
Translation — Sahih International
Or do they say, "He invented it"? Rather, it is the truth from your Lord, [O Muhammad], that you may warn a people to whom no warner has come before you [so] perhaps they will be guided.
