Refutation of Disbelievers' Claims

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.

وَمَا هُوَ بِقَوْلِ شَيْطَـٰنٍ رَّجِيمٍ

And it [i.e., the Qur’ān] is not the word of a devil, expelled [from the heavens].
