for example, samaritanism is a religion closely related to judaism, as druzism, ahmadiyya or alevism are to islam. the bahá'í faith considers itself a successor to the traditional abrahamic religions. somewhat related to christianity are many gnostic sects, as well as mandaeism. kurdish religions such as the various yazdani faiths are quasi- or post-abrahamic, syncretic, and may trace some portions of their theology to iranian religions and in some cases zoroastrianism.
