5– Murder of Zakia’s soul:

One of the definite signs of the advent of the Imam of the Age (may God hasten his fate) is the killing of Zakia’s soul, that is: the supreme Sayyid who is martyred in Mecca, between the pillar and the innocent position.

It is narrated from Imam Mohammad Baqir (as) that he said: One of the signs of reappearance is the killing of a man from the lineage of the Messenger of God, peace be upon him and his family, among his pillars and position and his name is Muhammad ibn al-Hasan (Zakia soul).

It is reported that the distance between his death and the appearance of the vulva will not be more than fifteen days. This soul of Zakia is one of the companions of Hazrat Mahdi (pbuh) who sends him to the people of Mecca before his reappearance to give the good news of his reappearance to the people and because he announces the reappearance of Hazrat Mahdi (pbuh), the people of Mecca attack him and He is killed.
