TEHRAN (Asremrooz): among the children of Imam Musa –Ebn-Jafar (peace be upon him), Ali-Ebn-Musa and Hazrat Fatemeh Kobra(peace be upon them) have specific characteristic in order to continue their father’s thought.
She was born on first day of the month of Zee al-Qa'adah in the year 173 A.H./789 A.D., in the holy city of Madinah Munawwarah. Her holy father was martyred in the Baghdad prison at the hands of the Abbasid caliph Harun al-Rashid after undergoing long term of imprisonment and tortures. After the martyrdom of her holy father she came under the care of Imam Reza (peace be upon him), her elder brother.Hazrat Masoumeh was about 10 years old when her father Imam Musa Kazim (peace be upon him) passed away. After her father’s death, Hazrat Masoumeh had a strong connection with her brother Imam Reza (peace be upon him),.
Imam Musa al-Kadhim (peace be upon him), named his daughter Fatimah, for the sake of love and special attachment he had with his grandmother Fatimah Zahra (peace be upon him). Fatimah's purity, modesty, and piety were such that after sometime she was referred as "Ma'soomah" (the infallible). This was because like her honorable Father, she used to keep away from all evils and sins.
Fatimah Ma'soomah was growing under the shelter of her father and dear mother and was day by day learning new things from both of them. If the father of Fatemah was the Imam of the Muslims and was matchless in his piety and chastity, then her mother was also pious and faithful who had accomplished her essential studies of Islam in the school of the wife of Imam Ja'far Sadiq (peace be upon him). In those days she was the most intelligent amongst all women and it was for reason that the mother of Imam Kadhim (Hamideh) asked him to propose and marry her.
Hazrat Fatimah Ma'soomah took advantage of studying in the presence of her father, brother and pious mother. All her young life was full of Islamic education. Every Friday Muslims would come to Medina with their religious questions. After getting their questions answered by Imam Musa al-Kadhim (peace be upon him), they would return to their town. Incidentally, once Imam Kadhim(peace be upon him), was away and Imam Ridha (peace be upon him), was also not around. The Muslims without getting their questions answered were returning home very sad. Fatimah Ma'soomah noticed the sadness and took the papers from them and answered their questions. The Muslims became happy and left
Imam Sadiq (peace be upon him) said: soon a lady by the name Fatimah from my family will be buried in Qum. Heaven becomes obligatory on one who visits her.
Imam Reza ( peace be upon him) loved his sister so much that he stated “ he who visits Hazrat Masumeh in Qom, he visits me”.
