Ali al-Ridha
It has been commonly held that Maruf Karkhi who was converted to Islam through Ali al-Ridha is one of the foremost figures in the golden chain of most Sufi orders. He was a devoted student of Ali al-Ridha and is an important figure for Sufism and Shi'ism. According to Corbin, although at the end of the Safavid period a Ni'mat Allahi Sufi from India named Ma'sum been sent by his spiritual master, Shaykh Shah 'Ali Rida Dakhani, to Iran and settled with his family at Shiraz, to restore the Ni'mat Allahi order in Iran, however the Sufi order while owes its name to Shah Ni'mat Allah Wali, goes back originally to the Eighth Shia Imam, the Imam 'Ali Rida through Ma'ruf al-Karkhi.
