What is the ruling on saying "Sayyid al-Akwan" (Master of the Universes) for the Prophet, peace and blessings be upon him?

The true Master of the Universes is Allah Almighty, because He is the Creator and Administrator of the universe. Some scholars have used the term (Master of the Universes) for the Prophet, peace and blessings be upon him, as Sheikh Hafiz al-Hakami did in the poem "Sullam al-Wusul." However, applying this term to the Prophet, peace and blessings be upon him, involves a form of exaggeration, and it is more appropriate to suffice with saying "Master of Humanity" or "Master of the Children of Adam" and similar phrases.
