Imam Hussain’s (PBUH) blood on the ground of Karbala made the courage and bravery immortal. There are Yazidi ones during different eras, and having the responsibly of guarding his covenant, Hussaini ones would defend the Truth . After the events of Ashura, the history got unrest and it wouldn’t calm down till the Reappearance of the Promised Savior. Hussain of the era will reappear and annihilate the Yazidi tyrants of the era and we would not break our covenant like Kufans.
