Then Allah sent a crow digging up the earth so that he might show him how he should cover the dead body of his brother. He said: Woe me! do I lack the strength that I should be like this crow and cover the dead body of my brother? So he became of those who regret.

And He it is Who created the heavens and the earth in six periods-- and His dominion (extends) on the water-- that He might manifest to you, which of you is best in action, and if you say, surely you shall be raised up after death, those who disbelieve would certainly say: This is nothing but clear magic.

Say: No one in the heavens and the earth knows the unseen but Allah; and they do not know when they shall be raised.
