While Imām Mahdī (mGehr)’s Hujjah [Mahdaviiat] was clear, why did some Shiites consider “Nafs al- Zakiyyah1” or “Muḥammad ibn Hanafiyyah” as Imām Mahdī (mGehr)?!
Although in some Aḥādīth which are about Imām Mahdī (mGehr)’s rise, by the Messenger of God (pbuh&h) and his Ahl al Bayt (pbu th), it has been clarified that he is definitely the son of 11th Imām “Askarī (pbuh)”, because the people knew all Ahl al Bayt (pbu th) as “The best guide for people” and “Guided By God”; therefore, facing cruelty and violation, they took refuge to one of them as “Imām Mahdī (mGehr)” [It was a sort of psychological need to a divine Imām]. They would also take some other people with themselves.
