Amir-ul-Mu’minin’s special sword is part of the precious heritages of the holy Imams, which is now in the hands of Hazrat Mahdi (a.t.f.s.). Besides, the hand-written Qur’an by Amir-ul-Mu’minin (a.s.), the walking stick of the holy prophet (s.a.w.a.), the rings of Imams and the heritages of past prophets, all in all, are in the protection of Hazrat Mahdi (a.t.f.s.). This is so while his inheritance from the past prophets and Imams takes the colour of material as well as spiritual aspect. He is the inheritor of material belongings as well as spiritual knowledge and powers.
Each of the material heritages of prophets is a sign among the Divine signs by means of which Hazrat Mahdi (a.t.f.s.) exhibits his powers and manifests the miracles of all the prophets and Imams (a.s.).
Imam Baqir (a.s.) said:
“When the ‘Qaem’ rises, he shall do so while possessing the flag of the holy prophet (s.a.w.a.), ring of Soloman (a.s.) and stick of Moses (a.s.).” 
Imam Sadiq (a.s.) too has said:
“There is no miracle of any prophet or Imam but that Allah will manifest it through our “Qaem” until the argument is finalized for the enemies.”
