(91:8) And inspired it [with discernment of] its wickedness and its righteousness, (91:9) He has succeeded who purifies it, (91:10) And he has failed who instills it [with corruption]. (91:11) Thamud denied [their prophet] by reason of their transgression, (91:12) When the most wretched of them was sent forth. (91:13) And the messenger of Allah [Salih] said to them, "[Do not harm] the she-camel of Allah or [prevent her from] her drink." (91:14) But they denied him and hamstrung her. So their Lord brought down upon them destruction for their sin and made it equal [upon all of them].
