And We have already sent messengers before you. Among them are those [whose stories] We have related to you, and among them are those [whose stories] We have not related to you. And it was not for any messenger to bring a sign [or verse] except by permission of Allah . So when the command of Allah comes, it will be concluded in truth, and the falsifiers will thereupon lose [all].
Have they not traveled through the land and observed how was the end of those before them? They were more numerous than themselves and greater in strength and in impression on the land, but they were not availed by what they used to earn.
