And certainly Allah made a covenant with the children of Israel, and We raised up among them twelve chieftains; and Allah said: Surely I am with you; if you keep up prayer and pay the poor-rate and believe in My messengers and assist them and offer to Allah a goodly gift, I will most certainly cover your evil deeds, and I will most certainly cause you to enter into gardens beneath which rivers flow, but whoever disbelieves from among you after that, he indeed shall lose the right way.

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 when your Lord announced that He would certainly send against them to the day of resurrection those who would subject them to severe torment; most surely your Lord is quick to requite (evil) and most surely He is Forgiving, Merciful.
