علي بن موسى الرضا
There are many important imamzadehs. Two of these are Fātimah bint Mūsā, the sister of Imam Ali al-Ridha, the eighth Twelver Imam, and Zaynab bint Ali, daughter of Ali, considered by Shi'i Muslims to be the first Imam and by Sunni Muslims as the fourth Rashid. Imamzadehs are not traditionally women.
