I want to know the answer to the following question:
What Arabic term did the Umayyad caliphs use to refer to themselves?
All the background I'm provided with is that "In this respect it is notable that the Umayyad caliphs referred to themselves not as khalifat rasul Allah ("successor of the messenger of God", the title preferred by the tradition), but rather as khalifat Allah ("deputy of God").". Is that enough to answer the question?
