A lady from my children whose name will be Fatima, daughter of Musa, will die in Qum. On the Day of Judgement this lady will intercede for all my Shi’a to enter Heaven.
Imam Sadiq (A)
Excerpt from 'Lady Fatima Masuma (a) of Qum':
The father of Lady Fatima Masuma (A) was the 7th Imam – Imam Mūsā al-Kāđim (A). It has been recorded in history that Imam al-Kāđim (A) had numerous children.
Shaykh Mufīd (d. 413 A.H) writes that Imam al-Kāđim (A) had 37 children (whom he has named), 19 sons and 18 daughters; and that two of these daughters were named Fatima – Fatima al-Kubrā and Fatima al-Sughrā.
Sibt ibn Jawzī, the famous 8th century scholar of the Ahl al-Sunnah, narrates that four daughters of Imam al-Kāđim (A) were named Fatima: Fatima al-Kubrā, Fatima al-Wustā, Fatima al-Sughrā and Fatima al-Ukhrā.
Fatima al-Kubrā is the very same Lady Fatima Masuma (A) buried in Qum.
It is narrated that Fatima al-Wustā is buried in Isfahān and her Haram is called Sittī Fatima (near Chāhār Sūq Shīrāzī-hā).
Fatima al-Sughrā is well known as “Bībī Heybat”. She is buried in Azerbaijan, where the beautiful dome and gardens at her shrine were destroyed during the era of Communist Russia.
Fatima al-Ukhrā, who is also known as Fatima Tāhira, is buried in Rasht, Iran.
The contemporary researcher, `Allāmah Shaykh Muhammad Taqī Tustarī writes: 'Amongst all the children of Imam al-Kāđim (A), other than Imam Ali al-Ridā (A) there was no one equal in status to Lady Fatima Masuma (A).'
