Passage: The second major event of the early reign of Abd al-Malik was the construction of the Dome of the Rock in Jerusalem. Although the chronology remains somewhat uncertain, the building seems to have been completed in 692, which means that it was under construction during the conflict with Ibn al-Zubayr. This had led some historians, both medieval and modern, to suggest that the Dome of the Rock was built as a destination for pilgrimage to rival the Kaaba, which was under the control of Ibn al-Zubayr.
What was the first major event of the early reign of Abd al-Mali?
