He was imprisoned by his erstwhile ally and kinsman, Caliph Marwan II, in 745 and presumably died in incarceration.
During his father's reign, he led raids against the Byzantine Empire along the caliphate's northern frontier, including in 710/11 and the winter of 714/15.
In 714, he was appointed amir al-hajj by his father, putting him in charge of the Hajj pilgrimage to Mecca.

Marwan II subsequently compelled the largely Qaysi troops of Qinnasrin to arrest and hand over Bishr and the latter's full brother Masrur who became captives.
