Either fiqh is a way to structure human society with divine wisdom with enough flexibility to get God's people on top or it is a set if arbitrary rules used like magic spells to get into a place far away called heaven.

They want you to think that treating the Sharia like the first makes you a modernist kaffir while treating God's moral code like the second, makes you a pious member of the group of The Chosen One.

Fiqh maximalization on the basis of old manuals is destructive and makes any victory impossible.
