Fatema Mæ'sume

Fātimah bint Mūsā al-Kādhim (Arabic: فاطمة بنت موسى الكاظم‎‎), commonly known as Fātimah al-Ma‘sūmah (Arabic: فاطمة المعصومة‎‎) or Fatemeh Ma'sumeh (Persian: فاطمه معصومه‎‎, "Fatimah the Innocent"), Masuma-e-Qum (معصومه قم), and Hadrat Masumah (1st Dhul Qi‘dah 173 AH – 10th or 12th of Rabī’ al-Thānī 201 AH; approximately March 22, 790 AD – November 7 or 9, 816 AD), was the daughter of the seventh Twelver Shī‘ah Imām, Mūsā' al-Kādhim and sister of the eighth Twelver Shī‘ah Imām, ‘Ali ar-Ridhā. Every year, thousands of Shi'i Muslims travel to Qom to honor Fatima Masumeh at her shrine.

Despite having been infallible, Fatima Masumeh is not considered one of the 14 most holy figures in Shia Islam. Yet, her brother Imam Ali al-Ridha gave her the title "Masumeh", which means infallible or sinless. In Shi'ism, women either become saints by their own accord or because they are the sisters, daughters, or wives of other saints. Fatima Masumeh became a saint because of her closeness to her brother Imam 'Ali al-Rida and her father Imam Musa al-Kadhim. However, Fatima Masumeh also has her own reputation of holiness and wisdom. She is said to have been learned in various Islamic sciences and the teachings of Muhammad, and to have transmitted many hadiths from her family members.

Fatima Masumeh is honored in many hadiths, or teachings, from Shi'i Imams that proclaim the benevolence of visiting her shrine in Qom. Her brother Imam 'Ali al-Rida stated that visiting the shrine of Fatima Masumeh is equal to visiting him, demonstrating his honor of his sister. Other Imams declare that anyone who visits Fatima Masumeh's shrine will surely go to heaven. More miracles are reported to occur at her shrine in Qom than at the burial place of any other prophet or imam.
