So that the followers of the Book may know that they do not control aught of the grace of Allah, and that grace is in Allah's hand, He gives it to whom He pleases; and Allah is the Lord of mighty grace.

He it is Who caused those who disbelieved of the followers of the Book to go forth from their homes at the first banishment you did not think that they would go forth, while they were certain that their fortresses would defend them against Allah; but Allah came to them whence they did not expect, and cast terror into their hearts; they demolished their houses with their own hands and the hands of the believers; therefore take a lesson, O you who have eyes!
