The
historiography of early Islam refers to the study of the early
history of Islam during the 7th century, from
Muhammad's first revelations in AD 610 until the disintegration of the
Rashidun Caliphate in AD 661, and arguably throughout the 8th century and the duration of the
Umayyad Caliphate, terminating in the incipient
Islamic Golden Age around the beginning of the 9th century.
