Is it permissible to use titles such as "His Majesty" for kings, and what is the ruling on writing names like "Abd al-Nabi" or "Abd al-Rahman" in full; and does the one who says or writes them incur sin?

There is no harm in saying or writing "His Majesty" for one who deserves it, without arrogance or admiration. The majesty of a creature differs from the Majesty of the Creator.

It is not permissible to be named with names that signify servitude to other than Allah, such as "Abd al-Nabi" (servant of the Prophet) or "Abd al-Fadil" (servant of the virtuous). However, it is permissible to write these names in official transactions or work-related contexts, as the scope of reporting is wider than that of naming. The Prophet (peace be upon him) said: "I am the son of Abd al-Muttalib," as a statement of fact, not as an establishment of a new name.

It is permissible to name a person "al-Hamid" (the Praised) with a meaning appropriate to them.

As for the names of Allah that are exclusively His as proper nouns, it is not permissible to name others with them. However, for names that have a general meaning and where individuals can vary in their possession of that quality, such as "al-Malik" (the King) and "al-Aziz" (the Mighty), it is permissible to name others with them.
