Surah Ash-Shu'ara, verse 141

فَكَذَّبُوهُ فَأَهْلَكْنَـٰهُمْ ۗ إِنَّ فِى ذَٰلِكَ لَـَٔايَةًۭ ۖ وَمَا كَانَ أَكْثَرُهُم مُّؤْمِنِينَ ﴿١٣٩﴾

And they denied him, so We destroyed them. Indeed in that is a sign, but most of them were not to be believers.

وَإِنَّ رَبَّكَ لَهُوَ ٱلْعَزِيزُ ٱلرَّحِيمُ ﴿١٤٠﴾

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

إِذْ قَالَ لَهُمْ أَخُوهُمْ صَـٰلِحٌ أَلَا تَتَّقُونَ ﴿١٤٢﴾

When their brother Ṣāliḥ said to them, "Will you not fear Allāh?

إِنِّى لَكُمْ رَسُولٌ أَمِينٌۭ ﴿١٤٣﴾

Indeed, I am to you a trustworthy messenger.
