Narjis bint Yashoua (, ', 'Narjis' meaning narcissus) was the wife of Hasan al-Askari (217–260 AH, c. 832 – 890 CE) and the mother of the final Imam of Twelver Shia Islam. Her name has been recorded as Narjis, Saiyra, Katrina, Lilliana, Malika, and primarily Anna'", in books. More sources have described her as a "Roman (i.e. Byzantine) princess" who pretended to be a slave so that she might travel from her kingdom to Arabia. Mohammad Ali Amir-Moezzi, in the "Encyclopædia Iranica", suggests that the last version is "undoubtedly legendary and hagiographic".
