And to the Thamūd [We sent] their brother Ṣāliḥ. He said, "O my people, worship Allāh; you have no deity other than Him. There has come to you clear evidence from your Lord. This is the she-camel of Allāh [sent] to you as a sign. So leave her to eat within Allāh's land and do not touch her with harm, lest there seize you a painful punishment.
Then Allah sent to the tribe of Thamūd their brother Ṣāliḥ, to call them to belief in the Oneness of Allah and to worship Him alone. Ṣāliḥ said: 'O People! Believe in Allah alone, you have no other God worthy of being worshipped. I have come to you with a sign proving the truth of what I have brought you: namely a camel which will come out of a rock. It has an allocated time to drink from the water, and for you a seperate time to drink. Allow her to eat within Allah’s land and do not harm her in any way, or a painful punishment would befall you.'
