> 91:13 And the messenger of Allah said: It is the she-camel of Allah, so let her drink!
[...]
> 7:73 And to (the tribe of) Thamud (We sent) their brother Salih. He said: O my people! Serve Allah. Ye have no other God 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
[...]
> 11:64 O my people! This is the camel of Allah, a token unto you, so suffer her to feed in Allah's earth, and touch her not with harm lest a near torment seize you.
