He it is that drave forth those of the people of the Book who disbelieved from their homes at the first gathering, Ye imagined no that they would go -forth; and they imagined that their fortresses would protect them against Allah. Wherefore Allah came upon them whence they reckoned not, and cast terror in their hearts so that they made their houses desolate with their own hands and the hands of the believers. So learn a lesson. O ye endued with insight!
