Khalifa ibn Khayyat is the author of the earliest extant Arabic chronicle. The work principally deals with fighting between Arab groups, external conquests, and administrative matters. After the death of each caliph it lists the persons who held office (as governors, judges and secretaries) during his reign; it also notes who led the pilgrimage in each year, the death of prominent persons (included those who died in major battles), and natural phenomena.

Events are for the most part narrated quite briefly and the work was presumably intended as a useful guide to Islamic history and a complement to his biographical dictionary of scholars, which also survives. Carl Wurtzel translated the portion of Ibn Khayyat's chronicle that relates to the Umayyad period (AD 660-750) for his PhD thesis (Yale, 1977). The translation is of a high standard and is well annotated. The introduction is useful for providing an overview of the life and oeuvre of Ibn Khayyat and a survey of his sources, as well as a consideration of the apparently pro-Umayyad bias of the author.

Ibn Khayyat's chronicle is relatively early in date. It also has quite wide scope, especially as regards its narration of the Arab conquests, ranging from Spain across the Mediterranean and all the way over to Central Asia. It is by far our earliest Muslim source for these campaigns.
