Imam Ali ibn al-Husayn was a living embodiment of ‘Ashura as he witnessed his father, brothers, and companions cruelly massacred on the plains of Karbala. While having to live in such sorrow, the Imam lived through a difficult era as he strove to mend the socio-political conditions of his society. Throughout these events, Imam Sajjad tried to prevent corruption, as the rulers inhibited the spread of Islam through crowd manipulation. He also accomplished his role as a guide and benefactor by teaching Islamic principles, emphasizing the concept of Imamate, resisting moral corruption, looking after the needy, and setting slaves free. His role as a spiritual guide through his practice of continuous prayers gained him the title Imam Sajjad (The Prostrating Imam) and resulted in a collection titled Sahifah al-Sajjadiyyah (The Psalms of Islam). This article offers a brief biography of the Imam, a brief history of the events after ‘Ashura, and the Imam’s accomplishments in reviving the Muslim community.
