Shu'ba ibn al-Hajjaj

Shu'ba ibn al-Hajjaj, known by the byname Abu Bistam, was one of the most influential transmitters of hadith — the reported sayings and practices of the Prophet Muhammad — in the early Islamic period. Tradition holds that he was born around 82-86 AH (roughly 701-705 CE) in or near Wasit, a city in central Iraq, and that he was a mawla (a non-Arab client or freedman attached to an Arab tribe, here the Azd) rather than an Arab by descent. As a young man he moved to Basra, then a leading centre of religious learning, where he lived, taught, and died.

He is chiefly remembered for a method rather than a doctrine. Where earlier transmitters often passed on traditions broadly, Shu'ba is reported to have insisted on examining who was in a chain of narration and rejecting reports from those he judged unreliable — an approach later scholars treat as a foundation of the discipline of narrator-criticism (al-jarh wa'l-ta'dil, "disparaging and accrediting" transmitters). For this rigour the later tradition credits the scholar Sufyan al-Thawri with calling him amir al-mu'minin fi'l-hadith, "commander of the faithful in hadith." His narrations are quoted throughout the major Sunni collections, including those of al-Bukhari and Muslim.

He is said to have studied in the circles of figures such as al-Hasan al-Basri, and to have taught the next generation of Basran critics, among them Yahya ibn Sa'id al-Qattan and Abd al-Rahman ibn Mahdi. Not all contemporaries accepted every judgement of his; some, the sources note, questioned particular transmissions. He died in Basra in 160 AH (776 CE).
