The Word of Monotheism in the Viewpoint of the Principalists (Usolyeen) and Imam Khomeini

One of the topics of the theology which is discussed in the discipline of Usul is the word of monotheism or the phrase La ilaha illallah (There is no god, but God). The present article is an attempt to explain the concept of exception, the meanings of the letter “la” as well as the possibility of the elimination of its news in order to shed light on the questions and queries about the word monotheism (unity). Attempts have been made in this article to advance the viewpoints of the ulema particularly those of Imam Khomeini about the said questions and queries.
