A government based on the Quran
Imam Ali (PBUH), in an expressive statement, describes the Quranic government of Imam Mahdi (PBUH) as the following:
At a time when passion (people’s selfishness) rules, Imam Mahdi (PBUH) will rise up and will replace passion with guidance and salvation of souls and in an age when self-ideology is prioritized over the Holy Quran, will drag the attentions towards the Quran and makes it rule over the society.
