﴿ وَإِلَىٰ ثَمُودَ أَخَاهُمْ صَٰلِحًۭا ۗ قَالَ يَٰقَوْمِ ٱعْبُدُوا۟ ٱللَّهَ مَا لَكُم مِّنْ إِلَٰهٍ غَيْرُهُۥ ۖ قَدْ جَآءَتْكُم بَيِّنَةٌۭ مِّن رَّبِّكُمْ ۖ هَٰذِهِۦ نَاقَةُ ٱللَّهِ لَكُمْ ءَايَةًۭ ۖ فَذَرُوهَا تَأْكُلْ فِىٓ أَرْضِ ٱللَّهِ ۖ وَلَا تَمَسُّوهَا بِسُوٓءٍۢ فَيَأْخُذَكُمْ عَذَابٌ أَلِيمٌۭ ﴾

“AND UNTO [the tribe of] Thamud [We sent] their brother salih He said: "O my people! Worship God alone: you have no deity other than Him. Clear evidence of the truth has now come unto you from your Sustainer. "This she-camel belonging to God shall be a token for you: so leave her alone to pasture on God's earth, and do her no harm, lest grievous chastisement befall you.”

And We sent to Thamūd Thamūda read without declining the noun as denoting the tribe of Thamūd itself their brother Sālih. He said ‘O my people worship God! You have no god other than Him. Truly there has come to you a clear proof an illustration from your Lord of my truthfulness this is the she-camel of God a sign for you lakum āyatan is a circumstantial qualifier operated by the import of the demonstrative noun hādhihi ‘this’ they had asked him to make it come out of a specific rock which they had designated. So leave her to feed throughout God’s earth and do not touch her with harm either by hamstringing or beating her lest you be seized by a painful chastisement.
