text_A: Early Islamic literature rarely speculates on the origin of the "mukhannathun" or on moral issues, but it does have a lot to say about accepting their ways and manners. It seems there may have been some variance in how "effeminate" they were, though there are indications that some adopted aspects of feminine dress or at least ornamentation. One later hadith states that a Muslim "mukhannath" who had dyed his hands and feet with henna (traditionally a feminine activity) was banished from Medina, and executed outside of its walls for his behavior.
text_B: Given how common, or rare, commentary about the mukhannathun is in literature of the time, is it safe to assume that Mohammed himself never noticed or remarked upon their customs?
NO.
