Arrangement Of Quran
Had the sequence been left to the original order, then it would’ve created ambiguity w.r.t adressees of the Quran. Since the phases of sarguzisht had varied w.r.t adressees of Kalam. Therefore, it would’ve resulted in a jungle of confusion as to who is being addressed and at what stage of Inzar. And even if Sahaba were to teach the historical background of Surahs to their students ( which actually they did through akhbar-i-ahad ), it would’ve created the same problem of relying on something external to understand the meaning of Quran. In Farahi Discourse, the context, adressees and the stage of Inzar are all to be understood from the Kalam itself ( Which establishes Quran’s status as being Furqan and Meezan ). The tradition that you referred to, would’ve resulted in a parallel source of understanding Quran ( which exists even now in the form of ‘tafseeri riwayaat’ and ‘Asar narrations’ ).
