He then listed the attributes of the Mahdi and said: “HE IS YOUR GREATEST REFUGE, THE ONE WHO HAS THE MOST KNOWLEDGE AMONG YOU AND THE MOST CONCERNED FOR HIS FRIENDS AND THOSE HE LOVES. My Allah! Make his appearance a virtue for the elimination of sorrows and bring the fragmented community back together through him! If Allah grants you success, RUN TO SWEAR ALLEGIANCE (TO JOIN) HIM AND NEVER ABANDON HIM. IF SUCCESSFUL, IF YOU REACH HIM AND ATTAIN THE PATH TO SALVATION, NEVER GIVE UP ON HIM. And pointing to his chest he said ‘How I wish to see him.’
(Sheikh Muhammad bin Ibrahim Nomani, al-Ghaybah al-Nomani, p. 252)
HAZRAT MAHDI (AS) WILL POSSESS MAJESTY, CALM AND DIGNITY.
...HAZRAT MAHDI (AS) WILL POSSES GREATER KNOWLEDGE AND FOREBEARANCE THAN ANYONE ELSE. Hazrat Mahdi (as) bears the name of the Prophet and his moral values are those of Muhammad (saas).
(Al-Mahdi Al-Mawud, Vol. 1, pp. 281-282, 266 and 300)
