It was...
It was, most probably, in this period that al-Radi and his brother al-Murtada were brought to al-Shaykh al-Mufid by their mother for being educated in fiqh and other religious sciences. And perhaps it was during this period that Abu Ishaq Ibrahim ibn Ahmad al-Tabari, a Sunni Maliki faqih, gifted a house to al-Sayyid al-Radi when he came to know that the brightest of his pupils had no residence of his own for his wife and had to live with his mother.
During the period of his father's imprisonment, al-Radi composed many poems to pay tribute to him. Abu Ahmad was set free by Sharaf al-Dawlah, son of Adud al-Dawlah, while proceeding to Baghdad from Kirman in 376/ 986-87 to depose his brother Samsam al-Dawlah, who also had not released Abu Ahmad and other captives.
It is to be noted that 'Adud al-Dawlah was a Shiah of Zaydi inclination, but for him, like most of the monarchs of the Muslim world, political expedieney and interest were much more important than the matter of faith.
As even the 'Abbasid caliph of his time was afraid of al-Radi's connection with the Prophet's Family and his influence among the people, probably 'Adud al-Dawlah was also afraid of al-Radi's father, fearing that if at any time he aspired to wrest power out of his hands he could pose a serious challenge to him. Abu al-Faraj al-Jawzi has also referred to the arrest of Abu Ahmad in the course of recording the events of the year 369/979-80.
The influence of Abu Ahmad and his family assumed greater dimensions in the eyes of the rulers due to the tense and highly explosive situation ereated by the rivalries and conflicts between the Sunnis and the Shi'ah and the Turks and the Daylamites. These clashes resulted in looting, killing and burning of al-Karkh, a predominantly Shi'ah locality, for one week continuously, in the year 361/971-72, that was repeated in 363/974.
Moreover, there was a conflict between Bakhtiyar al-Daylami, the vizier, and 'Adud al-Dawlah, in which the latter emerged victorious later. Abu Ahmad was on good terms with Bakhtiyar also, which was a sufficient reason for 'Adud al-Dawlah to regard him as an enemy. Abu Ahmad died at the age of 97 in 403/1O12-13, and the high offices held by him fell upon al-Radi. From his mother's side al-Radi belonged to a lineage that was more distinguished for its political activities than the former.
His grand-father al-Nasir al-Saghir al-Husayn ibn Ahmad (d. 368/979) was a pious and respected man.
