Is it permissible to use the word "Al-Akram" (the Most Generous/Noble) when addressing a manager in a letter?

Using the term "Al-Akram" (the Most Generous) in addresses is not a naming but rather a superlative description of the addressee over their peers, and it does not imply absolute perfection in generosity. Its use does not necessitate prohibition, but precaution and perfect etiquette prevent it. Some scholars consider it impolite to describe anyone other than Allah as "Al-Akram," and many virtuous people prefer to use the term "Al-Mukarram" (the Honored) instead.
