I understand that in Shia Islam the first three Rashidun are grasped as unlawful political successors of Muhammad in leading the Ummah and in any case unfit to lead justly by their verity to replace Ali as caliph.
I have read in the past that some "Shia" scholars alleged the Quran as not entirely divine due to Uthman's edits but this paradigm came up from individual "Shia" persons, not from any of the current Shia sect.
Is there a current Shia sect that rejects Uthman's edit of the Quran so to accept only some part of the Quran or to use an edited Quran of their own?
