Saeed bin Jubair narrated that I asked Abdullah bin Abbas (may Allah be pleased with him) about "Surah At-Tawbah," so he said: This is the Surah of Repentance or the one that exposes. In this Surah, it kept being revealed: "Some people are like this and some people are like that," until people thought that this Surah would not leave anyone unmentioned, rather it would expose the secrets of all. Saeed narrated that I asked about Surah Al-Anfal, so he said: It was revealed about the Battle of Badr. He narrated that I asked about Surah Al-Hashr, so he said: It was revealed about the Jews of the tribe of Banu Nadir.
