The word shubha is used to denote different meanings, such as similarity and identity, complexity and ambiguity: But the use of the term is different in Fiqh (jurisprudence) and science of scholastic theology. Shubha in jurisprudence is used only in the sense of doubt. While in theology, “shubha is a theological argument that makes it difficult to distinguish right and intentionally or unintentionally, challenges the religious beliefs of a religion by mixing or creating similarities between right and wrong or good and bad. Also, shubha has features, such as the use of a seemingly simple and straightforward argument system, persistence despite reaching logical response, exploitation of abnormalities and rare things, referring to the behavior of the public, being more effective on the masses, growth in non-responding environments, and power of rapid expansion and growth. These characteristics have made shubha, in the opinion of theologians, to be very dangerous; so much so that some have considered answering to shubha as one of the goals of science of scholastic theology.
