After the demise of Prophet Muhammad (PBUH), the Muslims were divided regarding whom they should follow as their political and religious leader. The Sunnis followed the Prophet's companions whilst the Shias followed the 12 Holy Imams chosen by God. The Shia Imams were from the lineage of Prophet Muhammad (PBUH) from his only surviving daughter, Lady Fatimah (SA). Successive Shia Imams lived amongst the Muslims for generations and guided them to the true Islamic teachings of the Prophet. All of the Shia Imams were respected by the Muslims for their spirituality, divine knowledge, and being the progeny of the Prophet. The Imams were a symbol of resistance against the injustice and oppression of the Umayyads and the Abbasids. As a result, the Imams endured many calamities and hardships. They were harassed, imprisoned, and martyred by the Umayyad and the Abbasid caliphs. This book reviews the lives of these 12 Holy Imams and provides an overview of their religious, social, and political achievements.
