(40) Ali bin Ahmad narrated from Obaydillah bin Musa al-Alawi from Muhammad bin Abdul Jabbar from Safwan bin Yahya from Abu Sa’eed al-Mukari that al-Harith bin al-Mugheera an-Nasri had said: I said to Abu Abdullah as-Sadiq : “With what will the imam (al-Mahdi) be recognized?” He said: “With calmness and gravity.” I said: “What else?” He said: “You will know him by (executing) halal and haram (permissibility and impermissibility), by the need of people to him whereas he will never need any one and that the weapon of the Prophet (S) will be with him.” I said: “Is he a guardian and a son of a guardian?” He said: “He is not but a guardian and a son of a guardian.”
