Studying the Sources of Shiʿa Narrations in al- Tibyān

Regarding the interpretive narrations of al-Tibyān, Shaykh Ṭūsī, in his method, pays serious attention to the Ahl al-Bayt's hadiths and the interpretive narrations of the Companions and Successors. When quoting Shiʿa interpretive hadiths, he uses indications such as "our Companions"(Aṣḥābunā), "our Imams" (Aʾimmatinā), and "our news" (Akhbārunā). According to the results, in quoting Ahl al-Bayt's hadiths, the commentaries of al-Maṣābiḥ Maqribī, Qumī, Ayāshī, and Wāqidī book are the definite sources of al-Tibyān. Also, some of the Shiʿa narrative collections including Kāfī, some works of Shaykh Mufīd, Shaykh Ṣadūq, etc. can be considered as its probable sources. In addition, the existence of some Shiite narrators' names such as Jābir ibn Yazīd and Abi al-Jārūd at the beginning of some narrations can indicate that he has used their commentaries too. Besides, in some cases, Ahl al-Bayt's hadiths have been transmitted from Ṭabarī commentary to al-Tibyān. Shaykh Ṭūsī has used abundantly non-Shiite sources such as Jāmiʿ al-Bayān, and mentioned their author's name; on the contrary, he hasn't specified the names and works of the Shiite authors. This method should be affected by the governing atmosphere of Baqdād, where this work has been written and it should be considered in relation to his proximity approach.
