From the children of the seventh Imam Hazrat Fatimah Ma'soomah bint Musa ibn Jafar (a.s) has a special position after Imam Ridha (a.s). Due to her faith, virtuousness and training under the guardianship of Imamate she reached such a position that the Masoom (Imam) gave her the title of Ma'soomah (infallible) , and because of her worship and abstemiousness she acquired the status of intercession. This is why the most learned scholars, the greatest Maraje', and the real Gnostics are humbly standing at her holy shrine saying:
Oh Fatimah intercede for us in heaven since you have reached a dignified status from a high rank with Allah.
There is a tradition that states that out of the eight gates of heaven, one will open towards Qum and due to her intercession all Shias will go to heaven. Her eighteen years of life was spent with suffering and difficulties. Had to bear separation from her beloved brother.
In tradition it is excessively mentioned that whoever visits (does ziyarat of) Hazrat Ma'soomah, heaven is incumbent upon that person and this position is obtained by her after the fouteen Ma'soomeen.
Imam Ridha (A-S) has said:
Whoever visits her (does her ziyarat) acknowledging her right, is entitled to heaven.
In Kamil al ziyarah it is quoted form Imam Ridha (a.s)
Whoever does the ziyarat of Ma'soomah in Qum it is as though he/she has done my ziyarat
Majlisi quoted in Bihar:
Whoever visits Ma'soomah it is as though he/she has visited me. It is equal to heaven
Ma'soomah stayed in Qum fro seven days only. Due to her brief stay and her holy shrine, Qum was blessed with such a special position that Imam Sadiq (a.s) says:
Haram of God
Haram of Rasool
Haram of Imam Ali
and the Haram of Ahlul bait (peace be upon them) is Qum
According to the quote of Imam Musa ibn Jaffar (a.s)
Qum is refuge of Aal Muhammad (s.a.w)
A group of people from the town of Rai came to Hazrat Abi Abdillah (a.s) and said that we are the settlers o Rai.
Imam (a.s) said: Welcome to our brother from Qum
They said again: "We are from the town of Rai. Imam (a.s) replied with the same statement as before. This act repeated several times, then Imam (a.s) said that:" God's haram is kufa, main and my progeny's haram will be Qum. Qum is a small Kufa. From the eight gates of heaven three open towards Qum. One chaste lady from our family, named Fatimah will be buried there. Her status and position is such that due to her intercession all shias will go to heaven.
It is due to the blessed lady Masoomah, that after the city of knowledge Najaf al ashraf the greatest center and learning institute of the Shia world is in Qum, surrounding her holy shrine where more than twenty thousand students, the most learned scholars are busy studying, teaching and conducting research. This city has embraced numerous libraries and learning institutes with in its vicinity.
Hazrat Ma'soomah used to live in Medina. When Ma'moon Abbas summoned Imam Ridha(a.s) to Khurasan , she found this separation heavy to bear. After one year she left for Khurasan in order to see her brother. When they reached Saveh, which is about SIXTY-TWO KM from Qum, she felt ill. Musa ibn Khazray took this dignified lady to their home. Ma'soomah passed seven days in Qum suffering from illness until finally she departed from the transient abode on the 10th of Rabi uthanni.
