I want to know the answer to the following question:
Along with Rhodes, what Byzantine possession did Muawiyah occupy?
All the background I'm provided with is that "Muawiyah also encouraged peaceful coexistence with the Christian communities of Syria, granting his reign with "peace and prosperity for Christians and Arabs alike", and one of his closest advisers was Sarjun, the father of John of Damascus.". Is that enough to answer the question?
Answer: no
