Abū Jaʻfar Moḥammad Ibn ʻAlī Ibn Ḥosayn Ibn Mūsā Ibn Bābiwayh Qomī (Shaykh Ṣadūq)

Born and Family
Mohammad, son of Ali, son of Husein son of Bābiwayh-e Qummī, known as Sheikh-e Sadūq, was born in 305 Hegira in Qum, in a family which was adorned by the brand of knowledge and piety.
Sheikh-e Tūsī has described the story of Sadūq’s birth as follows: “Ali, son of Bābiwayh had married with his cousin, but she did not bear any child for him. In a letter to Sheikh Abul-Qāsim Husein Ibn-e Rūh (the incumbent representative of the occulted Imam, Mahdī Aj.F.) he asked him to submit his request to His Holiness Imam Mahdī (Aj.F) to pray to Allah to bestow him decent and knowledgeable children. After a while there was a respond, issued from His Holiness Imam Mahdī (Aj.F) stating that, “You will not have any child from your present wife, but you will soon possess a female slave who is from Deylam (northern Iran), and she will give birth to two knowledgeable sons for you.”
Sheikh-e Sadūq himself has also stated the same story in form of a narration in his book “Kamāluddīn”, and further commented: “Whenever Abū Ja’far Muhammad, son of Alī Al-Aswad saw me going to my teacher, told me: “There is no wonder to see such enthusiasm in you for acquisition of knowledge, because you were born on the supplication and request of Imam Mahdī(Aj.F.).”His Father
His honorable father, Alī son of Husein son of Bābiwayh-e Qummī, was one of the most outstanding Islamic scholars and jurisprudents of his age.
Although there were many scholars and narrators living in Qum at that time, Alī son of Bābiwayh (the father of Sheikh-e Saduq), as a pious scholar who had exposed some miraculous deeds, was the torchbearer of guidance and religious authority for Islamic jurisprudence (Marja’īyyat). He had a stall in the bazaar of Qum, and piously earned his livelihood by trading and selling things. He assigned a part of day for teaching precepts of Islam and narrating Hadīths (Traditions).Teachers

Scientific Position
Sheikh-e Sadūq is a great dignitary in the Islamic world and a brilliant luminary of science and virtue.
He lived close to the era of infallible Imams; therefore, collected Traditions and Narrations of AHL-UL-BAYT (the infallible household of the Holy Prophet of Islam A.S.) and compiled premium and precious works, and thus presented valuable services to Islam and Shi’a.
Sheikh-e Sadūq had a chance to take advantage of the last twenty years of the blessing life of his father. During this period he made the best use of the presence of his father and other scholars of Qum to acquire wisdom and knowledge. He was at the age of 22 or 23 when his father passed away. After that, he took the heavy burden of responsibility to promulgate the Hadīths (Traditions and Narrations) of the AHL-UL-BAYT (A.S.) and guide the Islamic community to the right way. Thus, a new episode started in his life.

Sayings of Great Men
-Sheikh-e Tūsī introduces Sadūq as follows: “He was a glorious sage who knew the Hadīths by heart. He was completely familiar with RIJĀL (study of biographies of the trustworthy narrators of Hadīths in the chain of documentations). He was a marvelous critic in the chain of Hadīths, and had no counterpart amongst Islamic Ulamā (sages) with regard to his knowledge of Hadīth and his good command of Islamic science. He has written about 300 books in different fields of Islamic science.”
-Najāshī, the great scholar in the field of RIJĀL, writes about him: “Abū Ja’far (Sheikh-e Sadūq), an inhabitant of Rey, is a Faqīh (Islamic Jurisprudence) and brilliant figure of Shi’a in Khorāsān. He had a trip to Baghdād while he was quite young, nevertheless all great scholars went to learn Hadīths from him.”
-Allāmah Bahrānī states: “A number of our companions such as ‘Allāmah Hillī’ in his ‘Mukhtalaf-ush-Shi’a’, ‘Shahīd’ in his ‘Sharhe Irshād’, and ‘Sayyid Muhaqqiq-e Dāmād’ believe that even the ‘Loose Traditions’ (Hadīth-e Mursal) narrated by Sheikh-e Sadūq are correct and trustworthy; one can depend on them and put them into practice, because, for the same reason that the Loose Traditions cited by Ibn-e Abī Umayr were approved, the Loose Traditions by Sadūq are to be accepted as well.”

Demise
This great sage, as the last descendant of Sadūq family, after a long blessing life, passed away in 381 Hegira and traveled to the everlasting world.
