I Have not read the entire part, but reading the dialogue between Hazrat Umar and defeated Governor of Iran, Harmazan in the introduction part gives an impression of expressive misapprehension against cognition. I don’t know how Brother Sidqi will take this note!
Winning or losing war have their verifiable proven physical reasons, while convictions in belief while in war may or may not be as distinctly decisive as reason. Like the series of defeats of Muslim Arabs against Israel were the results of hardware and astute preparedness. Faith in God alone but without means doesn’t win a war. War needs concentrated, all-encompassing, goal oriented critical, strategic and tactical means to prepare for it. The article however doesn’t state those reasons for Iranian defeat but merely aggrandize Muslims belief in God alone. It leads to believe that reason and faith are not parallel to each other, but mutually exclusive. It reads like Naseem Hijazi novels of Islamic conquests swelling the chest filled with elation but without its reason.
