An-Naml 27:45

وَلَقَدْ أَرْسَلْنَآ إِلَىٰ ثَمُودَ أَخَاهُمْ صَـٰلِحًا أَنِ ٱعْبُدُوا۟ ٱللَّهَ فَإِذَا هُمْ فَرِيقَانِ يَخْتَصِمُونَ

Walaqad arsalnā ilā thamūda akhāhum ṣāliḥan ani uʿ'budū l-laha fa-idhā hum farīqāni yakhtaṣimūna

And We had certainly sent to Thamūd their brother Ṣāliḥ, [saying], "Worship Allāh," and at once they were two parties conflicting.
