"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."— Yusuf Ali translation
