What is the ruling on naming a girl "Malak" or "Malaak," and is there sin in calling her by it, and what is the interpretation of the noble verse: "Indeed, those who do not believe in the Hereafter name the angels with the naming of females," and its relation to the matter?

The first point is that a girl should not be named "Malak" or "Malaak." There is no harm in calling someone by that name if it has not been changed, because it is an act of informing, not an act of creating a name, and the scope of informing is broader than that of creating.

As for the interpretation of the verse: The intent is that they (the polytheists) call every angel female, as Al-Baghawi said: "Meaning, by calling them female when they said: 'Indeed, they are daughters of Allah.'" Some scholars, like Ibn Al-Qayyim, mentioned that naming women with the names of angels might be overtly forbidden, because it imitates the polytheists in their assertion that angels are daughters of Allah. This includes naming a girl: "Malaak," "Malaqah," or "Malak."
