Thamud - Ancient Arab tribe mentioned in the Quran

"The Thamūd were an ancient Arabian tribe or tribal confederation that occupied the northwestern Arabian peninsula between the late eighth century BCE, when they are attested in Assyrian sources, and the fourth century CE, when they served as Roman auxiliaries. They are mentioned in contemporary Mesopotamian, Classical, and Arabian sources, including in inscriptions in a temple erected in the 160s for the god ʾlhʾ by the Thamūd themselves. It is possible that multiple unrelated groups took on the name of Thamūd. They probably spoke Old Arabic. - Wikipedia"
