Salaam Fellow Br/Sr.
Sayidah Masumah al-Qum, her full name Sayidah Fatimah Masumah bint Muwsa Kaazim 
was the daughter of Imam Muwsa al-Kaazim ibn Jaafar as-Saadiq and the sister of Imam Ali ar-Rida ad-Daamin . Her titles are Masumah and Mansurah. Her holy shrine lays in Qum al-Muqaddas, on the route to Mashhad al-Ashraf, Iran.
Was Sayidah Masumah's mother Hadrah Najmah (the mother of Imam Ali ar-Rida) ? Did Sayidah Masumah marry and have children? How did Sayidah Masumah pass away and what was her age at the time? Also any other information, narration and event in her honour would be highly appreciated.
Jazaakallah.
yes Sayidah Masuma was Imam Ali Razas real sister..and she didnt marry and died young..i heard she passed away when her brother was sent to Iran and she couldnt live without him..so she went to Iran in search for him with all of her brothers and sisters, on the way, a little before they reached Iran, the caravan was poisoned but she did eventually reach Iran. on reaching she saw everyone was wearing mourning clothes, when she was told of her brothers death, she had a fever because of the poison and shock and passed away.
also i heard that she had immense knowledge and the women of the Ahlul Bait too have narrated sayyings and she has plenty...
there was this incident where Imam Musa Kadhim was once out of the city and one man came to the house.he kept asking for the Imam and went back when told he wasnt there..on the last day that he came, he told the servant that it was importatnt for him to meet the Imam as he had come from a faraway place and his tribe sent questions that needed answering. Sayyidah Masuma told the servant to bring the questions and answered every one of them. when the man left he met the Imam on the way. the Imam asked him if he could see the answers to the questions, and when he read them, he said 'I am a very proud father to a daughter who at the age of 6 could answer these questions.'
