Different opinions concerning Hazrat Mahdi (as) will be put forward but these opinions will then be united
The leader of the time Al-Mahdi (Hazrat Mahdi (as)), whom different views shall combine to follow, and shall join between various minds, through him the rights of your intimate friends shall be extracted, through him you shall retaliate the evils of your enemies and fill the Earth with good and justice through him Allah shall expand His servant’s favour and gratefulness. And return the fact to its place with honoured and praised and shall return the religion as new through his hand.
(Sayyid Murtadha Muctahidi Sistani, Nashr Almas Publications, p. 343)
Hadith refers to rising of different opinions about Hazrat Mahdi (as). Many different opinions concerning Hazrat Mahdi (as) will gradually coincide in a single opinion. Hadith accounts for establishment of rights of Muslims, who are brothers, with an uphill struggle, by means of Hazrat Mahdi (as). It is understood by this expression that Muslims would be living in an environment of oppression. By Allah’s inducement of Hazrat Mahdi (as), there will be an environment of justice, and security in the world. This expression tells us that before Hazrat Mahdi’s (as) cause, injustice and lovelessness will rule the world. Allah’s consent and gladness will rise by means of Hazrat Mahdi (as). Religion of Islam will turn to its roots and Islamic moral values will prevail.
