To the Thamud People (We sent) Salih, one of their own brethren. He said: "O my people! Worship Allah: ye have no other god but Him. It is He Who hath produced you from the earth and settled you therein: then ask forgiveness of Him, and turn to Him (in repentance): for my Lord is(always) near, ready to answer." [Quran 11:61]
