As-Sajdah - 32:3

أَمْ يَقُولُونَ افْتَرَاهُ بَلْ هُوَ الْحَقُّ مِن رَّبِّكَ لِتُنذِرَ قَوْمًا مَّا أَتَاهُم مِّن نَّذِيرٍ مِّن قَبْلِكَ لَعَلَّهُمْ يَهْتَدُونَ
[32:3]
Or do they say: He has forged it? Nay! it is the truth from your Lord that you may warn a people to whom no warner has come before you, that they may follow the right direction.
Or do they say, "He has forged it"? Nay, it is the Truth from thy Lord, that thou mayest admonish a people to whom no warner has come before thee: in order that they may receive guidance.
Or say they: He hath invented it? Nay, but it is the Truth from thy Lord, that thou mayst warn a folk to whom no warner came before thee, that haply they may walk aright.
