Angels-MUNKIR AND NAKIR

Munkir and Nakir are two blue-eyed black angels found in Muslim tradition.
Their special job is to examine the souls of the recently deceased
to determine if they are worthy of a place in paradise. The angels ask
the deceased “who is Muhammad?” The believers will have the correct
answer that Muhammad is Allah’s messenger. They will then be left in
peace until Resurrection Day. Those who fail the test—the sinners and
infidels—are subjected to torture until the Day of Resurrection.
