Shahadah, which is the Muslim declaration of faith, has a few different synonyms that may be used depending on the context. In some cases, it may be referred to as "tawheed," which is the concept of monotheism in Islam. "Kalimah" is another term used to refer to the shahadah, which roughly translates to "word" or "phrase" in Arabic. "Iman" is also sometimes used to describe the shahadah, which refers to one's faith or belief. Finally, the shahadah may be referred to simply as the "testimony," as it is a declaration of one's belief in one God and Muhammad as His prophet.
