Al Ihtijaj Tabarsi is an important classical work compiled by the renowned scholar Sheikh Abu Mansur Ahmad ibn Ali ibn Abi Talib Tabarsi. The book brings together various arguments and dialogues from Islamic history, involving the Prophet Muhammad (PBUH), Imam Ali (A.S.), and other members of Ahlul Bayt (A.S.), as well as other influential scholars. The title "Ihtijaj" means "protest" or "argument," and this work addresses key theological, philosophical, and political challenges faced by early Muslims. Through debates with non-Muslims and Muslims alike, it presents a defense of core Islamic principles such as monotheism, Imamate, and justice, while also refuting misconceptions and false allegations against Islam and the Prophet’s family. It offers valuable insights into the intellectual and theological discourses of early Islamic history, serving as a cornerstone for those who seek to understand the defense of Shia beliefs.
