Abd Allah ibn al-Mubarak

Abd Allah ibn al-Mubarak (118 AH / c. 736 CE - 181 AH / 797 CE) was one of the most respected scholars of the early Islamic world, remembered as a transmitter of hadith (reports of the words and deeds of the Prophet Muhammad), a jurist, a merchant, and an ascetic who repeatedly served on the Byzantine frontier. He was born in Merv, a great caravan city in Khurasan (today in Turkmenistan); his father, Mubarak, is described in the sources as a freedman (mawla) of non-Arab origin, so the family stood somewhat outside the Arab tribal elite.

Tradition holds that he began life as a merchant, then poured his wealth and energy into travel for knowledge. The biographer-traditions report that he studied across Kufa, Basra, the Hijaz, Syria, Yemen and Egypt, and that the early scholar Ahmad ibn Hanbal praised no one as more eager to seek knowledge. He taught often in Baghdad. He is credited with compiling an early Kitab al-Zuhd ("Book of Renunciation," on asceticism and piety) and a Kitab al-Jihad ("Book of Struggle/Warfare"), and several of his sayings and ascetic poems are widely quoted.

He combined this scholarship with periods of ribat (guarding the frontier) and campaigning around Tarsus and al-Massisa against the Byzantines. He died in 181 AH (797 CE), reportedly at Hit on the Euphrates, while returning from such a campaign. Later Sunni tradition gave him the honorific "commander of the faithful in hadith"; this is an esteem-judgment of later critics, not a contemporary office.
