O assembly of believers, remember the blessing of Allah the Exalted which He blessed upon you in -Medina- during the days of the Battle of the Confederates (Al-Ahzab)-and it is the Battle of the Trench-, when the polytheists gathered against you from outside -Medina-, and the Jews and the hypocrites from -Medina- and its surroundings, and they surrounded you, so We sent against the Confederates a severe wind that uprooted their tents and threw their pots, and We sent angels from the heaven whom you did not see, so the terror fell into their hearts. And Allah was All-Seeing of what you perform, nothing of that is hidden from Him.
