Narrated Sa'id bin Jubair: I asked Ibn 'Abbas about Surat Al-Tauba, and he said, "Surat Al-Tauba? It is exposure (of all the evils of the infidels and the hypocrites). And it continued revealing (that the oft-repeated expression): '.and of them .and of them'. till they started thinking that none would be left unmentioned therein". I said, "What about) Surat Al-Anfal?" He replied, "Surat Al-Anfal was revealed in connection with the Badr Battle". I said, "(What about) Surat Al-Hashr?" He replied, "It was revealed in connection with Bani an-Nadir".
