Characteristics of Imam Mahdi (a.s) are similar to those of Prophets.

Imam Sajjad (a.s) said:
"In our Qaim are found the characteristics of the Prophets (a.s). They are similar to those of our father Hazrat Adam (a.s), Hazrat Nuh (a.s), Hazrat Ibrahim (a.s), Hazrat Isa (a.s), Hazrat Ayyub (a.s), Hazrat Moosa (a.s), and Hazrat Muhammad Mustafa (saw). As regard to Hazrat Adam (a.s) and Hazrat Nuh (a.s) it is their long life. As regards to Hazrat Ibrahim (a.s) it is the secret birth and his staying away from the people. In case of Hazrat Moosa (a.s) it is the fear and his disappearance. In the case of Hazrat Isa (a.s), it is the controversy among the people about him, (some people believe that he is alive and on Allah's order resides on the fourth sky. While others allege that he was crucified.) In the case of Hazrat Ayyub (a.s), it is his perfection after his great test. And in the case of Hazrat Muhammad (saw), it is his reappearance with a sword."
