Is it permissible to describe the Prophet as "the Most Great," given that this attribute is one of the attributes of Allah, Almighty and Exalted?

There is no objection to saying, "The Greatest Prophet," because its meaning is "the greatest of the prophets." He, peace and blessings be upon him, is indeed the best of them and the master of the children of Adam. Allah Almighty is the All-Great, and none of His creation resembles Him: "There is nothing like Him, and He is the All-Hearing, the All-Seeing." Some of Allah's names and attributes may be applied to certain created beings with a restrictive connotation, such as His saying, exalted be He, about His Prophet, peace and blessings be upon him: "To the believers, he is kind and merciful," and His saying, exalted be He: "So We made him hearing and seeing," and His saying: "Then We gave him tidings of a forbearing boy."
