Kitab Al-Irshad also called the Book of Guidance is a biography of the lives of the 12 Shia Imams authored by the great classical scholar Shaykh Al-Mufid.
It describes the historical circumstances, miracles and virtues of the infallible Imams.
Shaykh Al-Mufid was a prominent Twelver Shi'a theologian. He was the son of Muallim, and was called Ibn Muallim. Mufid was taught by Al-Shaykh al-Saduq, Ibn Qulawayh, Abu Abdallah al-Basri and al-Rummani. He passed his teachings to his own students, including Sharif al-Murtada and al-Shaykh al-Tusi.
Only 10 of his 200 works have survived, including Amali, Al-Irshad, Al-Muqni'ah, and Tashih al-Itiqadat.
He described the situation and life of each Imam and the circumstances of each of their deaths. He mentioned the disappearance of the last Imam, Al-Mahdi (atf). The work reflects Mufid's perspective on history and hadith rather than theology or philosophy.
