"And to Thamud (We sent) their brother Salih. He said: O my people, serve Allah, you have no god other than Him. He brought you forth from the earth and made you dwell in it, so ask forgiveness of Him, then turn to Him. Surely my Lord is Nigh, Answering. They said: O Salih, thou wast among us a centre of (our) hopes before this. Dost thou forbid us to worship what our fathers worshipped? And surely we are in grave doubt about that to which thou callest us."
