Abū ʿAbd al-Raḥmān Abd Allah ibn al-Mubarak (Arabic: عَبْد اللَّه ٱبْن الْمُبَارَك, romanized: ʿAbd Allāh ibn al-Mubārak; c. 726–797) was an 8th-century traditionalist[3] Sunni Muslim scholar and Hanafi jurist.
[4] 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.
[5][6] His father, named Mubarak, was of Indian[7] 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.
It is said that ʿAbdullāh left his hometown of Merv, and while living in Hamadhān, went on to visit and speak often in Baghdad.
He was also known for defending Islamic borders (see ribat) on the frontiers of Tarsus and al-Massisah.
