The author of 'Eqdud-Durar' (chapter three) narrates from Harith-ibn-Mughaira Nazri as such: I told Hussein-ibn-Ali: By what wign should we recognize Mahdi?
He replied: By his calmness and dignity.
In the same book, he narrates from Hafiz Abu Muhammad Hussein (from the book 'Masabeeh') that Ka'ab al-Ahbar said: 'Like an Eagle with its two wings, Mahdi will be humble for the sake of Allah'.
In the eighth chapter of the same book, he narrates from Na'eem-ibn-Hemad (from the book 'Fatan') who narrates from Ta'oos as such:-
'Amongst the signs of Mahdi is this that he would be strict with his officials and generous and kind with the indigent.
In section three, chapter nine of the same book' he narrates from Na'eem-ibn-Hemad (from the book 'Fatan') that Abu Rumiyah said: 'Mahdi will show kindness to the poor and will caress them.
Again in section three, chapter nine of the same book he narrates from Hussein-ibn-Ali (A.S.) as such: 'When Mahdi emerges nothing will judge between him and the Arab and the Quraish except the sword. For what reason do they make haste in Hazrat's emergence!? I swear by Allah that Mahdi will not wear but coarse and rough clothes and will not eat but bread made of barley and death will be hidden beneath his word.
