59:2

It is He Who drove the disbelievers from among the People of the Book (reference is to the Jewish tribe of Banu Al-Nadir) out of their homes at the first banishment. You did not think that they would ever go out; and they thought that their fortresses would defend them from Allah, but the wrath of Allah came to them from where they never expected – which casted such terror into their hearts – that they destroyed their homes by their own hands as well as by the hands of the believers. So learn a lesson from this example! O the people of insight.
Meaning:-
Banishment: to expel from place, to send (someone) away
Fortress: a military stronghold,
Wrath: extreme anger.
