Ash-Shu'ara 26:193

إِنَّ فِي ذَٰلِكَ لَآيَةً ۖ وَمَا كَانَ أَكْثَرُهُم مُّؤْمِنِينَ

Indeed in that is a sign, but most of them were not to be believers.

وَإِنَّ رَبَّكَ لَهُوَ الْعَزِيزُ الرَّحِيمُ

And indeed, your Lord - He is the Exalted in Might, the Merciful.

وَإِنَّهُ لَتَنزِيلُ رَبِّ الْعَالَمِينَ

And indeed, the Qur'an is the revelation of the Lord of the worlds.

عَلَىٰ قَلْبِكَ لِتَكُونَ مِنَ الْمُنذِرِينَ

Upon your heart, [O Muhammad] - that you may be of the warners -

بِلِسَانٍ عَرَبِيٍّ مُّبِينٍ

In a clear Arabic language.

وَإِنَّهُ لَفِي زُبُرِ الْأَوَّلِينَ

And indeed, it is [mentioned] in the scriptures of former peoples.
