Surely (as for) those whom the angels cause to die while they are unjust to their souls, they shall say: In what state were you? They shall say: We were weak in the earth. They shall say: Was not Allah's earth spacious, so that you should have migrated therein? So these it is whose abode is hell, and it is an evil resort

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 had those who are unjust all that is in the earth and the like of it with it, they would certainly offer it as ransom (to be saved) from the evil of the punishment on the day of resurrection; and what they never thought of shall become plain to them from Allah.
