Angels, jinn and human beings are distinct categories of created beings. All depend on God, but their conditions and roles are not identical. Angels are described chiefly in terms of obedience; jinn and humans are addressed with commands and prohibitions under moral testing.
A well-known report describes angels as created from light, jinn from fire, and Adam from what has been related about him. These are statements of origin, not exhaustive scientific accounts from which every physical or psychological trait follows.
Unseen status or superficial resemblance of behavior does not merge separate categories into one species.
