The second book of the historical series for children pays attention to the wile character of Yazid the son of Mu'awiyah and the amazing character of his son Mu'awiyah. Yazid was the person responsible for the slaughter of our Imam Husayn (as) and the martyrs of Karbala. Unlike his grandfather and his father, the son of Yazid was a flower that flourished and bloomed in a heap of dirt.
