Praying For The Early Reappearance Of Imam Mahdi (A.S.)

Imam Hasan al-Askari (A.S.) said,

"By Allah they do not truly wish for his reappearance, and do not attain salvation. Except those, whom Allah the High and the Mighty, has made firm upon the sayings of their Imams, and gave them the tawfeeq (opportunity) to pray for the hastening of the reappearance."
(Kamaaluddin vol.2 Pg.384)
 
Imam Mahdi (A.S.) says:
"And pray more for an early reappearance. For certainly, in it, is your success."
(Kamaaluddin vol.2 Pg.485, Ghaibat-e-Toosi pg.292-293)
