What is the ruling on naming an email address "Muhammad Nabina" (Muhammad our Prophet), knowing that its owner might use it to enter group chats and fears it will be said, "Muhammad Nabina has left," and that he intends thereby for people to send blessings upon the Prophet so he may earn reward, and is it permissible to continue using it?

Combining the name "Muhammad our Prophet" in an email address and using it when speaking with women is not befitting the honor and reverence due to the Prophet, peace and blessings be upon him. Unsuitable things might be written, or a slip might occur. Therefore, this name should be changed out of protection and respect for the Noble Prophet. Furthermore, private conversations with women online are prohibited due to the corrupting influences that may result from them.
