And to (the people of) Thamud We (sent) their (kinship) brother Salih. He said: ‘O my people, always worship Allah; you have no other God except He. Indeed there has come to you from your Lord a clear Sign. This she-camel of Allah is a Sign for you. So leave her (free) to graze in Allah’s earth and do not touch her with an evil (intention) or a grievous torment will seize you.’
