﴿ وَلَقَدْ أَرْسَلْنَآ إِلَىٰ ثَمُودَ أَخَاهُمْ صَٰلِحًا أَنِ ٱعْبُدُوا۟ ٱللَّهَ فَإِذَا هُمْ فَرِيقَانِ يَخْتَصِمُونَ ﴾

“AND [likewise], indeed, We sent unto [the tribe of] Thamud their brother Salih [with this message]: “Worship God alone!” and, behold, they were [split into] two factions contending with one another.”

And verily We sent to Thamūd their brother in terms of his belonging to the same tribe Sālih with the following decree ‘Worship God!’ affirm His Oneness. And lo! they then became two parties quarrelling with one another over religion one party having become believers upon his arrival as messenger to them and the other party disbelievers.
