When all the signs of zuhoor has run its full course :
" Then God will bring together 313 men from distant lands to form the Imam's army. The Imam will have a sealed book containing the names of these men. The angel Gabriel will march at His right and the angel Michael shall march at His left. The Imam's two-pronged sword (Zulfeqaar) will emerge from its scabbard of its own accord. That will be the time of the declaration of the holy war. Then the enemies will be slain and the Prophet Jesus will return to earth from heaven. At the time of His appearance the Imam will be full of youth and vigour and He will carry the rod of Moses and the seal of Solomon. "
Imam Jafar-e-Sadiq A.S has said :
" I see the Mahdi and His companions as if they are threatened by danger from all sides , their supplies have exhausted , their clothes have worn out , their foreheads bear the mark of prostration. During the day they are as courageous as a lion and during the night they are busy in the adoration of Allah and their hearts are like solid pieces of iron. "
