Please read: Radiance of Vicegerency- Panahian by Ay. Sobhani When Imam Hussain gave permission to Hazrat Abbas to fight enemy forces. He requested Imam Hussain that can I go first and speak to the evil yazidi forces. Imam Hussain said go ahead Hazrat Abbas went and advice people to truth, to salvation. When Hazrat Abbas was speaking you can see the enemy forces being scared of Hazrat Abbas. Momin is who like Hazrat Abbas when speak enemy gets scared. If enemy is not scared that the person is either naive or sick. (Momin or Muslim should always make enemy scared because of his strength) One example of naive Muslim is from Imam Ali companion. Imam Ali told Abu Musa Ashari if you don\'t understand then don\'t interfere in those matters Be careful when you go there to mauwiyah forces all the evil people will come towards you and will surround you. Be careful don\'t deviate from your right path, the path of Imam Ali. What a catastrophe disaster Abu Musa Ashari brought with him to Islamic community at that time. Why he got so much of good name? The reason why Imam Ali was forced to choose him? Why he was imposed upon Imam Ali? I request all the youth of Islam please read the battle of Siffin against Imam Ali. Siffin war is Eye opener in many respect. Read from beginning till end Really an eye opener Book name Faorough Velayat Farsi (Radiance of Vicegerency English translation available at Amazon) by Ayatollah Sobhani (may Allah protect him) in detail about Life of Imam Ali and read part of Siffin war also.
