Abd Allah ibn al-Mubarak

Abū ʿAbd al-Raḥmān Abd Allah ibn al-Mubarak (عَبْد اللَّه ٱبْن الْمُبَارَك; c. 726–797) was an 8th-century traditionalist Sunni Muslim scholar and Hanafi jurist. Known by the title Amir al-Mu'minin fi al-Hadith, he is considered a pious Muslim known for his memory and zeal for knowledge who was a muhaddith and was remembered for his asceticism.

Biography
His father, named Mubarak, was of Indian or Turkic descent from Khurasan and became a Mawla or "client" of an Arab trader from the tribe of Banī Hanẓala in the city of Hamadhān. His mother was said to have been from Khwārizm. Mubarak later married Hind, a trader's daughter. Ibn al-Mubarak was born during the reign of Umayyad caliph Hisham ibn Abd al-Malik.

It is said that ʿAbdullāh left his hometown of Merv, and while living in Hamadhān, went on to visit and speak often in Baghdad. Ahmad ibn Hanbal commented that there was no one more eager to travel to seek knowledge than Abdullah ibn Mubarak. His teachers included Sufyān al-Thawrī and Abū Hanīfa. He wrote Kitāb al-Jihād, a collection of hadīth and sayings of the early Muslims on war, and Kitāb al-Zuhd wa al-Rāqa’iq, a book on asceticism. He was also known for defending Islamic borders (see ribat) on the frontiers of Tarsus and al-Massisah. He died in 797 at Hīt, near the Euphrates, during the reign of Harun al-Rashid.
