And O my people, ask forgiveness of your Lord and then repent to Him. He will send [rain from] the sky upon you in showers and increase you in strength [added] to your strength. And do not turn away, [being] criminals."
But if they turn away, [say], "I have already conveyed that with which I was sent to you. My Lord will give succession to a people other than you, and you will not harm Him at all. Indeed my Lord is, over all things, Guardian."
And to Thamud [We sent] their brother Salih. He said, "O my people, worship Allah ; you have no deity other than Him. He has produced you from the earth and settled you in it, so ask forgiveness of Him and then repent to Him. Indeed, my Lord is near and responsive."
They said, "O Salih, you were among us a man of promise before this. Do you forbid us to worship what our fathers worshipped? And indeed we are, about that to which you invite us, in disquieting doubt."
