Then your hearts became hardened after that, being like stones or even harder. For indeed, there are stones from which rivers burst forth, and there are some of them that split open and water comes out, and there are some of them that fall down for fear of Allah. And Allah is not unaware of what you do.

Or [consider such an example] as the one who passed by a township which had fallen into ruin. He said, "How will Allah bring this to life after its death?" So Allah caused him to die for a hundred years; then He revived him. He said, "How long have you remained?" The man said, "I have remained a day or part of a day." He said, "Rather, you have remained one hundred years. Look at your food and your drink; it has not changed with time. And look at your donkey; and We will make you a sign for the people. And look at the bones [of this donkey] - how We raise them and then We cover them with flesh." And when it became clear to him, he said, "I know that Allah is over all things competent."
