Imam Hussain (a.s)
As a young man, Imam Hussain (a.s) had many important duties. Before he became Imam one of his main activity in Madinah was to teach people the true Islam as well as how to connect with and obey Allah (s.w). An example of this is “Dua Arafa” it is a prayer which Imam Hussain read during hajj, and it taught people the true meaning of complete faith and obedience in Allah.
Imam Hussain (a.s) also managed a Trust. This means that he was in charge of keeping money safe and spending it in the cause of Allah. This trust was set up by Imam Ali (a.s) . It was set up to help the poor of the city by giving them food and many necessities of life. Therefore the imams created an Islamic Welfare system so that every hungry mouth had food, every naked person had clothes and everyone had somewhere safe to sleep at night.
After his brother Imam Hassan (a.s) was killed, Imam Hussain (a.s) became the Imam. Yazid ibn Maywa was the Caliph during the Imamate of Hussain (a.s). Yazid took the leadership of the Muslims by force and treated the people in a bad way, he also tried to destroy the rules of Allah by behaving badly.
Yazid tried hard to convince Imam Hussain (a.s) to give up his values and accept all the bad things that were being done. However Imam Hussain (a.s) was too noble to be threatened and he refused to give alliance to Yazid.
This made Yazid very worried and he threatened Imam Hussain(a.s) with death but this did not pressure him into accepting Yazid as a leader because the Imam was not afraid of death.
Imam Hussain (a.s) along with 72 followers was killed tragically in Karbala. His death is still remembered to this day ever year on the tenth of Muharram as the perfect stance against evil. Read more about what happened
