Hussain (PBUH) supporter of father
Hussain (PBUH) was about 32 when authority over Muslims was handed back to its rightful owner, as people paid their allegiance to Ali (PBUH). After some time, Imam Ali (PBUH) migrated to Kufah with his sons, and therein established the new capital of the Islamic government. During the span of his father's rule, Hussain (PBUH) was a true supporter and close assistant to his Imam and father in all political and military stages. He showed his utmost respect to his father and remained obedient to his commands at all times.
Hussain (PBUH) was trained and raised by the greatest defender of Islam; he had learned courage and bravery from his father; and he was seriously involved in the three wars during his father's Caliphate. In the battle of Jamal, Hussain (PBUH) was responsible for commanding the left side of the army of Amir al-Mu'minin (PBUH). He also achieved the first victory for the army of Ali (PBUH) in the battle of Siffin, where he and his companions freed theFurat (Euphrates) River.(2) Moreover, his role as a witness in the Hakamiyah arbitration between Muawiyah and his father, Imam Ali (PBUH), is clear proof of his active participation in the society.
Hussain (PBUH) a follower of his brother
After the martyrdom of Amir al-Mu'minin (PBUH), Imam Hassan (PBUH), by the will of Allah (SWT) and the recommendations of Prophet Muhammad (PBUH&HP), became the Imam and leader of the Muslims. He took responsibility in leading the Islamic societyand in preaching the religion of Allah (SWT).
As in the case of his father, Hussain (PBUH), like a true follower, continued to obey and respect his brother, while remaining firmly obedient in even the smallest matters. His manners and obedience towards his brother was so exemplary that historians have acknowledged and recorded many of the cases. In one example, they have recorded a narration from Imam Baqir (PBUH) as follows: "Due to the high respect that Imam Hussain (PBUH) held for his brother, he refrained from walking ahead of or talking before his brother, Imam Hassan (PBUH)."
As mentioned, Hussain (PBUH) was always in a state of obedience and support to Imam Hassan?s (PBUH) actions in political and social matters, especially concerning peace treaty with Mu'awiyah. Despite the unfaithfulness of all Muslims towards Imam Hassan (PBUH), Hussain, the son of Ali (PBUT), a known character in the world of Islam, defended Imam Hassan's (PBUH) decision on the peace treaty. Imam Hussain (PBUH) believed peace was the key factor in Islam's maintenance.
After the peace treaty, Hussain (PBUH) and his brother moved from Kufah to Medina, their birth place and city, in which the Prophet's shrine was built. In Medina, they continued to educate, enlighten, interpret, and explain the commandments of Allah (SWT) to the people. Not long after, however, Imam Hassan (PBUH) was poisoned and martyred by the order of Mu'awiyah. As Imam Hassan (PBUH) departed this world, the divine position of Imamate was once again passed to the most deserving. His brother Hussain (PBUH) became the next Imam in Islam.
