AS SAJDAH — Ayat 3

أَمْ يَقُولُونَ افْتَرَاهُ بَلْ هُوَ الْحَقُّ مِن رَّبِّكَ لِتُنذِرَ قَوْمًا مَّا أَتَاهُم مِّن نَّذِيرٍ مِّن قَبْلِكَ لَعَلَّهُمْ يَهْتَدُونَ

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.
