Allah Almighty revealed: And Noah's people, when they denied the Messengers We drowned them, and We made them as a sign for mankind. And We have prepared a painful torment for the Zalimeen (polytheists and wrong-doers, etc.). And (also) 'Ad and Thamud, and the dwellers of Ar-Rass, and many generations in between. And for each of them We put forward examples (as proofs and lessons, etc.), and each (of them) We brought to utter ruin (because of their disbelief and evil deeds). Surah 25: 37-39
Allah, the Exalted also revealed: Denied before them (i.e., these pagans of Mecca who denied you, 0 Muhammad) the people of Noah, and the dwellers of Ar-Rass, and Thamud, and 'Ad, and Pharaoh, and the brethren of Lot, and the dwellers of the Wood, and the people of Tubba'; everyone of them denied (their) Messengers, so My Threat took effect. Surah 50: 12-14
These verses indicate that the dwellers of Ar-Rass were destroyed as were the other people who refused to believe in the prophets of Allah.
