I understand that even stretching the meaning and perception infolded in this particular root too far will not yield "abbrogation/cancellation". The concept infolded in the root is to change the place of stationing of a thing, bring a thing on the place of another thing. A deed is performed, and the copy of the act is ready if the same is recorded in a book, and the written act can be seen by the performer of the act when he reads it. Recalling the memory is nothing but again seeing the past event; and thus the basic perception of the root is also there. After reading one's record everyone will "see" smallest act done by him during his life time.

Qur'aan was revealed/read/taught to the Messenger over a period of time in small bits and he kept reciting it to people immediately after receiving some Ayat. On every fresh revelation, the order of the sum total of the Book revealed upto that point of time was bound to get changed. Every time, placement of Ayat perforce needed to be changed to make the flow and continuity of reading.

Allah has described a principle that He follows. And change in the placement of Ayat was objected even in the days of revelation and people alleged the Messenger as "Muftar". The point has been made quite vivid in 16:101.

None of the 'ayat' of the universe get abrogated. It only changes the place. Knowledge is only of "ayat" and "ayat" of the Quran is the knowledge. Can "Knowledge" be treated as something liable to abrogation?
