Background

Al-Istibsar is one of the four major Shia collections of Hadith authored by Shaykh Tusi. According to Ali Nasiri, when Shaykh Tusi transferred to Baghdad and participated in the class session of Shaykh al-Mufid, he found conflicting Hadith (traditions) in Shia sources. Due to his nomination at the introduction of Tahdhib al-Ahkam, he wrote the book as a commentary on the Al-Muqni'ah for solving the crisis of contradiction in the Shia Islamic seminary in response to his friend request. Ali Nasiri give three reasons for selection Al-Muqni'ah by Shaykh Tusi: dignity of Al-Shaykh Al-Mufid, Al-Muqni'ah was based on Shia view and last reason is fruition of Al-Shaykh Al-Mufid’s intellectual and mental protection.
