Al-Fadl ibn Shadhan

He lived and grew up in Nishapur, as his nisbah al-Azdi indicates; he belonged to the Arab tribe of Azd.

[2] Al-Fadl and his family migrated to Baghdad when he was young, where he began his education, and later relocated to the neighboring city of Kufa, and then finally to Wasit.

After spending years in Iraq, al-Fadl returned to Nishapur and continued his educational activities, until he was exiled by the Tahirid governor for reportedly practicing Shi'ism.

[3] ibn Shadhan was also known as a jurist, and Mohagheq Hali has counted him among the first rank Imamiyyah jurisprudents.

As a narrator, Ibn Shazan is included in the series of records of many Imamiyyah hadiths, and Najashi has confirmed his endorsement.

[4] The most prominent scientific aspect of Ibn Shazan's personality is his speech, as Nasir al-Din al-Tusi mentioned him as a great orator.
