For reappearance of Imam of Time (Imam Zaman), there is a also a need for the existence of pious human beings, strong motives, unflinching faith, steadfast steps and enlightened hearts. The Imam of Time (a.s.) needs people who do not hesitate, waver and retreat in the face of difficult, painful and bitter situations. He needs them to engage in a great task, a task that is supposed to change the entire world. They should be able to withstand the difficulties. Therefore, a strong and formidable system is needed in which its people do not falter, and who are vigilant, clear-sighted and well-informed never wavering against hardship and difficulties. They are people who trust in God, and who are devoted, learned, God-fearing, submissive and humble against the weak and firm and resistant against the tyrants, the arrogant ones and oppressors.
