The one who claims to be the Shi'a of Imam Ali(AS), the culture of his life must resemble the culture of the life of Amir al-Mu'minin, Imam Ali (peace be upon him), Imam Ali must be his role model in his life and he has to follow him. The commander of faithful, Imam Ali (peace be upon him), during the days of his Caliphate used to walk in the avenues of Kufa on those hot and scorching days of summer. One day while he was passing by an alley that he saw a man who was treating his wife in cruel way; Imam Ali (AS) reprimanded the man and asked him to treat his wife in an intimate and affectionate way.
