He it is Who in the first assault drove forth the People of the Book that disbelieved from their homes at the first gathering of forces. You did not believe that they would leave; while they too thought that their fortresses would defend them against Allah. Then Allah came upon them from whence they did not even imagine, casting such terror into their hearts that they destroyed their homes by their own hands and their destruction was also caused by the hands of the believers. So learn a lesson from this, O you who have perceptive eyes!
