On the subject of party-political pluralism, imam Shirazi is quoted as follows:
· A party organisation becomes an obligatory duty if and when it becomes a prelude to establishing an Islamic government.
· If other methods become available to establish Islamic rule, party activity becomes an optional duty.
· Party activity is prohibited if it turns out to be a prelude to creating a parliament that does not rule according to Islamic Law.
· Party activity is prohibited if it aims at running the political machine of the country without reference to and acting according to the jurisdiction of religious scholars.
· Party activity is prohibited if it turns out to be a cause for bringing to power someone not acceptable to the majority of the nation, even if that someone was a learned and a just religious scholar.
· A single party's monopoly of power is also prohibited, because Islam is a religion based and built on Shura... the consultative system.
