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 to (the tribe of) Thamud (We sent) their brother Salih. He said: O my people! Serve Allah. Ye have no other Allah save Him. A wonder from your Lord hath come unto you. Lo! this is the camel of Allah, a token unto you; so let her feed in Allah's earth, and touch her not with hurt lest painful torment seize you.
Surah Al-A'raaf(7:73)
