Prophet Salih
Description of the People of Thamud
After the destruction of the Ad, the tribe of Thamud succeeded them in power and glory. They also fell to idol-worshipping. As their material wealth increased so, too, did their evil ways while their virtue decreased. Like the people of Ad, they erected huge buildings on the plains and hewed beautiful homes out of the hills. Tyranny and oppression became prevalent as evil men ruled the land.
Description of Salih
So Allah sent unto them His Prophet Salih (PBUH), a man from among them. His name was Salih Ibn Ubeid, Ibn Maseh, Ibn Ubeid, Ibn Hader, Ibn Thamud, Ibn Ather, Ibn Eram, Ibn Noah. He called his people to worship Allah alone, and to not associate partners with Him. While some of them believed him, the majority of them disbelieved and harmed him by both words and deeds. Salih directed them:
"O my people! Worship Allah, you have no other Ilah (god) but Him." (Ch 11:61)
