[Knowing about] the proofs and signs of The Emergence, can be effective at least in these two circumstances:

[First] when people are unaware of these issues; whether because of slacking off or neglect of the advertising agents.

[Second] when people haven’t  been directed to the right way based on the correct criteria, due to being captured in doubts’ trap, and providing atmosphere of intrigue by the false frontier and complexity of circumstances.

For example, the Prophet (pbuh&h) named ʻAmmār1 as the sign of the right front and stated,

“Know that, the group who kills ʻAmmār is of the false front”

[In this way], he taught the Muslims that whenever they are incapable of knowing the truth and false in the atmosphere of sedition,

[They can] recognize the truth and false, with respect to the sign mentioned above.

ʻAmmār ibn Yāsir ibn ʿĀmir ibn Mālik Abū al-Yaqzān  was one of the Muhajirun in the history of Islam[1] and, for his dedicated devotion to Islam’s cause, is considered to be one of the most loyal and beloved companions of Muhammad and ‘Ali; thus, he occupies a position of the highest prominence in Islam

Warning!

Those who wait until Sufyāni, Yamani and Khorasani rise up and then know what to do,

Are like those, who recognize the truth just after ʻAmmār is slaughtered or killed!

In fact, those who based on the reasons and attributes of the religion “had believed Ali (pbuh) was right, before the martyrdom of ʻAmmār “,

are too much different from those who “hadn’t been  awaken  before ʻAmmār’s blood was spilled on the earth! “»!
