The Messenger of Allah (ﷺ) was in Makkah along with Zaid bin Harithah, and Zaid bin "Amr bin Nufail passed by them. They called him to eat some food they had with them and he said: O son of my brother, I do not eat what has been slaughtered on stone altars. After that the Prophet (ﷺ) was never seen eating anything that had been slaughtered on stone altars. I said: O Messenger of Allah, my father was as you saw and as you heard; if he had lived to see you he would have followed you; pray for forgiveness for him. He said: “Yes, I will pray for forgiveness for him. He will be resurrected on the Day of Resurrection as one nation on his own."
