Al-A'raf - 7:73

وَإِلَى ثَمُودَ أَخَاهُمْ صَالِحًا قَالَ يَا قَوْمِ اعْبُدُواْ اللّهَ مَا لَكُم مِّنْ إِلَـهٍ غَيْرُهُ قَدْ جَاءتْكُم بَيِّنَةٌ مِّن رَّبِّكُمْ هَـذِهِ نَاقَةُ اللّهِ لَكُمْ آيَةً فَذَرُوهَا تَأْكُلْ فِي أَرْضِ اللّهِ وَلاَ تَمَسُّوهَا بِسُوَءٍ فَيَأْخُذَكُمْ عَذَابٌ أَلِيمٌ
[7:73]
And to Samood (We sent) their brother Salih. He said: O my people! serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord; this is (as) Allah's she-camel for you-- a sign, therefore leave her alone to pasture on Allah's earth, and do not touch her with any harm, otherwise painful chastisement will overtake you.
To the Thamud people (We sent) Salih, one of their own brethren: He said: "O my people! worship Allah: ye have no other god but Him. Now hath come unto you a clear (Sign) from your Lord! This she-camel of Allah is a Sign unto you: So leave her to graze in Allah's earth, and let her come to no harm, or ye shall be seized with a grievous punishment.
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.
