سورة Al-Hashr ( The Gathering ) - الآية 2

It is He Who expelled the disbelievers among the People given the Book(s) from their homes, for their first gathering; you did not expect them to leave, whereas they assumed that their fortresses would save them from Allah, so Allah’s command came to them from a place they had not imagined; and He instilled awe in their hearts, so they ruin their own houses by their own hands and at the hands of the Muslims; therefore learn a lesson, O those who can perceive!
