Ask the Israelites how many a clear sign have We given them; and whoever changes the favor of Allah after it has come to him, then surely Allah is severe in requiting (evil).

And Musa said: My Lord knows best who comes with guidance from Him, and whose shall be the good end of the abode; surely the unjust shall not be successful.

Have they not travelled in the earth and seen how was the end of those before them? They were stronger than these in prowess, and dug up the earth, and built on it in greater abundance than these have built on it, and there came to them their messengers with clear arguments; so it was not beseeming for Allah that He should deal with them unjustly, but they dealt unjustly with their own souls.
