Awaiting For The Reappearance Of Imam Mahdi (A.S.)

The Holy Prophet (S.A.W.S.) said, 
"The best worship is to await for the reappearance."
(Kamaaluddin vol.1 Pg.287, Faraidus Simtain vol.2 Pg.335) 
Amirul Momineen Ali (A.S.) said,
"Await for the reappearance and do not despair of the divine mercy. Because the best deed in the eyes of Allah, the Great and the Mighty is to wait for the Reappearance. It is the duty of those who are believers."
(Al Khisaal vol.2 Pg.616) 
Imam as-Sajjad (A.S.) said.

"The greatest success is to wait for the reappearance"
(Al Ihtejaj vol.2 Pg.154. Kamaaluddin vol.1 Pg.320) 
Imam Jafar as-Sadiq (A.S.) said,

"Those of you who die on this affair (shia faith) while you are in a condition of awaiting, are like those who has served the Qaem (A.S.) in his tent."
(Ghaibat-e-Nomani Pg.200) 
Imam Al-Jawad (A.S.) said,

"Certainly the Qaem from among us is the Mahdi. Awaiting for whom is obligatory during (his) ghaibat and obeying him is obligatory after his reappearance. And he is the third of my descendants."
(Kamaaluadw vol.2 Pg.377) 
Imam as Sadiq (A.S.) said,

"One who desires to be among the companions of the Qaem, must await, adopt piety and behave courteously. If he dies in such a condition before the advent of Qaem, then his reward will be similar to the one who attains his era. Hence, congratulations to you all for your relentless awaiting."
