He is the One Who collected the disbelievers from among the People of the Book (i.e. the tribe of Banu Nadir) from their houses and banished them the first time (from Madina towards Syria). You did not (even) think that they would go away and they thought that their strong fortresses would save them from (the seizure of) Allah. Then (the torment of) Allah came upon them from where they could not (even) imagine. And He (Allah) cast terror into their hearts (and thus) they ruined their houses with their own hands and the believers’ hands. So, learn a lesson (from it), O people of vision!
