Abu Abdallah Muhammad ibn Ibrahim ibn Mus'ab[1] (Arabic: ابو عبد الله محمد بن إبراهيم بن مصعب, died c. 850) was a Mus'abid military commander and provincial official for the Abbasid Caliphate.
[4] In the following year he led the caliphal troops that participated alongside Abdallah ibn Tahir's campaign against the rebel prince Mazyar in Tabaristan, and he fought a successful battle against Mazyar's lieutenant al-Durri, who he captured and executed.
[5] In 846 Muhammad was serving as proxy for his brother Ishaq in Baghdad when the attempted rebellion of Ahmad ibn Nasr al-Khuza'i took place.
Having received word of suspicious activity in the city, he sent an agent to investigate and quickly learned of the planned revolt.
Over the next several days his men rounded up Ahmad and other members of the plot, who were then transported to the caliph al-Wathiq for questioning.
