He whoever criticizes...
He whoever criticizes, maligns or rails at any of the Sahaba, especially those who are presidents of the state, is reckoned with the miscreants whom are to be not shared in food and drink and to neglect offering their dead bodies the ritual funeral prayer. This (juristic) rule is recorded in AtThehbi's AlMizan. There is no other conception or plan that can immunize Muawiya such as this Sahaba's ultimate decency conception.
Confronting Rivals of Muawiya and His Faction Adopting the Sahaba's ultimate decency conception secures victory, or tie at least, of Muawiya and his faction in any conflict against rivals.
For example, if Mohammed's progeny affirm that they are those from whom God has removed — mental and physical — uncleanness and purified them a thorough purification, Muawiya and his faction will immediately submit that simultaneous answer of considering Mohammed's companions — Sahaba — as decent that they do never lie, since they all shall be in the Paradise and none of them shall be sent to the hellfire.
If Mohammed's progeny assert that those who cause harm to them should be reckoned with those who cause harm to God, Muawiya and his faction shall provide that immediate answer that the Prophet (peace be upon him and his family) say: “They are harming me those who harm any of my companions..” In such a manner, the right is mixed with the wrong, the obedient with the disobedient and the virtuous with the sinful.
Engaging Muslims in Discrepancies In case Muawiya obtains the ability of emanating and broadcasting of the Sahaba's ultimate decency conception with its widespreading features, a party of Muslims will adopt, and another will contravene. Controversy, accompanied by fanaticism, will arise in each party's convictions.
This will lead to discrepancy and that each party record convictions that shall certainly be followed by a great deal of successors pursuing partisan imitation, claiming of defending the right and their own viewpoints. Regarding the conception involved, those who support such a conception are not necessarily supporting Muawiya. They claim of supporting the Prophet's companions.
Those who disagree to the conception, on the other hand, are acquitting themselves from the view of dissenting the Prophet's companions, indicating that their aim is divulging trickeries and political cabals hidden for the other party.
