Abu Huraira reported the Prophet as saying, "On the day of resurrection Abraham will meet his father Azar with blackness and dust on Azar's face and ask him if he did not tell him not to disobey him. His father will reply that now he will not disobey him, and Abraham will say, `My Lord, Thou hast promised not to put me to shame on the day when men are resurrected, but what shame is greater than my father being farthest from Thy mercy?' God most high will reply, `I have debarred the infidels from paradise.' Abraham will then be told to look and see what is under his feet, and he will see a bespattered hairy hyena which will then be taken by its legs and thrown into hell[*]." *Abraham's father will be turned into the form of a hyena so that Abraham will not see him being thrown into hell in his own form. Bukhari transmitted it.
