Deletion of Quran and Sunnah (2nd nomination)

Comment: The article now cites two additional secondary sources. I do not find the article to be significantly tainted with |original research.  When looking for substantiation of the statements in the article, I find it.  Yes, the article could use work. As the article is confusing, I can understand why the nominator might have thought that it was synthesis, but the debate between the Sunni and the Shia over the authenticity of Quran and Sunnah as a hadith is very real, and that is the topic of the article, as hidden as that may be
Stance: keep
