Is it true that every verse in the Qur'an beginning with "O you who have believed" does not signify true faith, but rather is metaphorical, as mentioned by Al-Baydawi?

The fundamental principle regarding শরীয়াহ (Islamic law) terminology is to interpret it according to its literal meaning and general applicability. The statement mentioned in the question, found in the book "Al-Ibhaaj," does not imply interpreting verses about faith metaphorically. Rather, it appears in the context of discussing the metaphorical inclusion of the lesser within the greater, as in the address to "the believers" or "the Ummah," which may refer to the majority. The author of "Al-Ibhaaj" emphasizes the requirement for all mujtahideen (qualified interpreters of Islamic law) to agree for a consensus (Ijma') to be valid. He discusses the disagreement regarding the formation of a consensus by the majority when a minority disagrees, based on the premise that applying general terms to the majority is metaphorical, not literal.
