Quran 24:11-25 Specifics About The Incident
With regards to the general question of the relationship between Qur’an, Sunnah, Hadith, established history and previous scriptures: The way it helps me to think about this issue is that, let’s say we are watching a movie. Along with the movie we are also provided with the director’s commentary. In the commentary we will not find all the details of the movie. For that the source of information is the movie itself. The commentary will cite the relevant scenes. In that sense the movie is complementing the commentary. But in order to understand the philosophy of the movie and the wisdom of particular scenes, there is no option but to consult the director’s commentary. So it like a guardian (muhaimin) over the movie. The commentary is the last word (mizan and furqan) in understanding a particular scene, not what we are understanding just by watching the movie itself. This is I think what the scholars of Farahi school try to emphasize when they approach Qur’an. To my understanding, what they are not saying is that the Qur’an is a closed book and there is nothing outside of it in order for us to understand its text. Obviously there are tons of things outside of Qur’an. Arabic language is outside (pre-requisite) of Qur’an, established history (history of the bani Israel etc) is outside of Qur’an, seerah of Rasulullah is outside Qur’an. But whatever is outside of it has to be seen through the lens of its text and context. Qur’an will have the last say about a particular concept or incident.
