  Translation

7. (And We said): "If you do good, you do good for your ownselves, and if you do evil (you do it) against yourselves." Then, when the second promise came to pass, (We permitted your enemies) to make your faces sorrowful and to enter the mosque (of Jerusalem) as they had entered it before, and to destroy with utter destruction all that fell in their hands.
