SAHIH BUKHARI
Volume 4, Book 55, Number 569 :
Narrated by Abu Huraira:
The Prophet said, "On the Day of Resurrection Abraham (pbuh) will meet his father Azar whose face will be dark and covered with dust.(The Prophet Abraham will say to him): 'Didn't I tell you not to disobey me?' His father will reply: 'Today I will not disobey you.' 'Abraham will say: 'O Lord! You promised me not to disgrace me on the Day of Resurrection; and what will be more disgraceful to me than cursing and dishonoring my father?' Then Allah will say (to him):' 'I have forbidden Paradise for the disbelievers." Then he will be addressed, 'O Abraham! Look! What is underneath your feet?' He will look and there he will see a Dhabh (an animal,) blood-stained, which will be caught by the legs and thrown in the (Hell) Fire."
