Are humans capable of knowing who a Jinn is in this life? Therefore, talking to one and the jinn aknowledges that he is a jinn. Same query for angels: do they exist among us, meaning, in the form of humans in society, but without humans knowing that they are indeed angels and not man?
Angels and Jinns can assume the form and shape of human beings. All human
beings do not recognise the angels and Jinns in the assumed form of human
beings.
and Allah Ta’ala Knows Best
