Author
Abu Jafar Muhammad Ibn Hasan Tusi known as Shaykh al-Ta'ifah or Shaykh al-Tusi was born in 996 AD in Tus, Iran. He was a Persian Shia Twelver scholar and authored two references of Shia collections of tradition, Tahdhib al-Ahkam and Al-Istibsar. Al-Shaikh al-Tusi died in Najaf on the 22nd of Muharram on 2 December 1067.
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.
Content
Shaykh Tusi explained his style in authoring the Tahdhib al-Ahkam in the introduction of it. According to viewpoint of Ali Nasiri, Shaykh Tusi authored this book basis on the six phases:
Mention the jurisprudential issues by keeping the structure of the book al-Muqni'ah by Shaykh al-Mufid
Recounting their proof except tradition (Hadith): Shaykh Tusi nominated to three type of proof, the Quran, Sunnah and consensus (agreement of the Muslim scholars basically on religious issues). The types of Quranic evidence was described by him. Also, according to his belief, Sunnah may contain Mutawatir tradition or Ahaad. In view of Shaykh Tusi, consensus referred to an agreement of Shia Muslim scholars.
Recounting the Hadith proof: one of the fundamental parts at Tahdhib al-Ahkam is to rely on the tradition that protects every issue.
Recounting the conflicting proof: rectifying the conflicting tradition was the main purpose of Shaykh Tusi for authoring this book. So he devoted the main part of his work to examine such tradition with a tradition that verifies every issue.
Describing the way of rectifying concordant and conflicting traditions: after determining this type of tradition, Shaykh Tusi inspect the way of rectifying.
Citing tradition in a bid to declare the interpretation: Shaykh Tusi used interpretation and rationalization to rectifying concordant and conflicting traditions.
Therefore, Shaykh Tusi proceeded to his work in three step:
Transmitting tradition that verifies every issue
Transmitting tradition that contrasts the first set of tradition
Transmitting tradition that affirms the interpretation

I: Ritual purity in Islam ((Taharah))
