Shaykhism

Shaykhism () is a term used by Shia Muslims for the followers of Shaykh Ahmad in early 19th-century Qajar Iran. While grounded in traditional Twelver Shiʻi doctrine, Shaykhism diverged from the Usuli school in its interpretation of key ideas such as the nature of the end times and the day of resurrection, the source of jurisprudential authority, and the proper hermeneutic to be employed in interpreting prophecy through the mystical writings of the Twelver Imams. These divergences resulted in controversy and ongoing accusations of heresy from Usulis and Akhbaris.

It has been described as a mystical strand of Twelver Shi'a Islam. , there remained a following in Iran, Iraq, Saudi Arabia, Kuwait and Pakistan.
