The word "Hāfizīn" in Q.82:10 refers to angels. In this verse, it is mentioned that there are noble, recording angels who are responsible for recording every action and deed that humans do throughout their lives. These angels are known as "Hāfizīn," which means "protectors" or "keepers" in Arabic. They are tasked with keeping a record of every single thing a person does, whether good or bad, and they will present this record on the Day of Judgment when each person will be held accountable for their actions. Thus, the term "Hāfizīn" specifically refers to angels who record the deeds of human beings.
