I wish we could dig up some of the original writings
about abrogation of two scholars:
- Shah Waliullah (the widely respected scholar who reduced the number of abrogated verses to 5).
- Abu-Muslim Al-Asfahani (the often dismissed early scholar who does not believe in the abrogation doctrine in principle).
I have not been successful in my search so far.
You found both, as you told me. Thanks for your perseverance. Shah waliullah (Dehlvi)'s book is available at https://ia601001.us.archive.org/33/items/abuyaala_fawz_dahlawi/fawz_dahlawi.pdf
and Al-Asfahaani's exegesis is available at http://www.4shared.com/file/60343575/cfd450d1/___.html
. Here are its particulars,
