Surah Ash-Shams, verse 10

فَأَلْهَمَهَا فُجُورَهَا وَتَقْوَىٰهَا ﴿٨﴾

And inspired it [with discernment of] its wickedness and its righteousness,

قَدْ أَفْلَحَ مَن زَكَّىٰهَا ﴿٩﴾

He has succeeded who purifies it,

كَذَّبَتْ ثَمُودُ بِطَغْوَىٰهَآ ﴿١١﴾

Thamūd denied [their prophet] by reason of their transgression,

إِذِ ٱنۢبَعَثَ أَشْقَىٰهَا ﴿١٢﴾

When the most wretched of them was sent forth.
