Haj Mirza Abul Qasim Mujtahid, the great Mirzai reached Imam Musa Kazem through twenty-seven mediators, as follows: Seyyed Abul Qasim Muhammad (27) bin Muhammad Kazim (26) bin Amir Muhammad Hossein (25) bin Sayyed Mohsen (24) bin Amir Salim. 23) Bin Berhadin (22) Bin Seyed Shahi (21) Bin Hasan (20) Bin Abdullah (19) Bin Ali (18) Bin Sulaiman (17) Bin Abdul Samad Ahmad (16) Bin Muhammad (15) Bin Dawud (14) Bin Ibrahim (13) Ibn Ali (12) Ibn Khalil (11) Ibn Ibrahim al-Samin (10) ... Ibn Musa al-Thani (Abi Sabaha) (3) Ibn Ibrahim al-Asghar (2) Ibn al-Imam Musa al-Kazim (1)
In the dynasty of Ibn Nasab, Ibrahim al-Samin (10) is buried near Toor Khormatour, 81 km from Kirkuk, and his grave is famous. Umka Ibrahim al-Asghar (2) has mentioned different places for his burial in different books, including in Lahijan, the current tomb of Jalal al-Din Ashraf, or in Yemen, and even in Karbala and Baghdad.
They have written about the reason why this family came to Zanjan: Shah Ismail Safavi, following the formalization of the Shia religion in the country, repeatedly requested the late Sheikh Ali bin Abdul Ali Karki, known as Mohaghig Sani and Mohaghig Karki, to come to Iran, but Mohaghig did not accept until It was renewed during the Safavid Shah Tahmasab reign (930-984 AH).
Mohaghegh accepted this time and came to Iran with a group of great scholars of the era, including Burhanuddin bin Seyed Shahi (22), who assigned Zanjan to him. Seyyed Amir Mohsen (24), the ancestor of the Mirzais and Mousavis of Zanjan and Isfahan, was one of the students of the late Mulla Mohammad Baqer Majlesi, the owner of Bihar al-Anwar (died 1110 A.H.) and one of the famous scholars of the age and era.
At the end of Shah Sultan Hossein Safavi's reign, during the Afghan revolution, Mahmoud Afghan looted the property of Seyyed Mohsen (24) and set fire to their house and mansion. The mansion of this late ancestor remains the same for many years, this Mirza Abul Qasim (known as Mirza) repairs that house and the said house is still in the dispute of the late Seyyid.
Seyyed Mohsen's grandson, Seyyed Mohammad Kazem (26), takes the steps of the nobles and attended the lessons of the late Mr. Seyyed Ali Sahib of Riyadh, until he reached the position of ijtihad and died at the age of three in Zanjan on the date of 1232 A.H. He left two male children: the late Seyyed Abul-Qasim known as Mirza (Jedmirzais) and the late Seyyed Muhammad Baqer (Jedmusoi of Zanjan). His grave is located next to his son in Mirzaei Tomb.
