According to the Holy Qur'an [5:3], this is the day when God Almighty "perfected" Islam as the religion by introducing Imam Ali (AS) as the next leader. That is why it is celebrated in honor of the first Shia Imam.
Ali (AS) was the cousin of the Prophet (PBUH) and is known as the first man to embrace the Prophet's call for Islam. According to Islamic sources, the Imam rooted out poverty and promoted an unprecedented justice system across the Muslim world during his 5-year rule-based in the Iraqi city of Kufa.
There are 12 Imams or religious leaders in Shia Islam, all believed to be preserving the legacy of the Prophet (PBUH) and his teachings. Mahdi (AS) is the last Imam, who is believed to be the apocalyptic savior of the world and is currently living in occultation.
