Sahih Muslim Book 1, Hadith Number 398.

Chapter : He who died with unbelief would be (thrown) into the Fire, intercession would be of no avail to him and the relationship of his favourites would not benefit him.

Anas reported: Verily, a person said: Messenger of Allah, where is my father? He said: (He) is in the Fire. When he turned away, he (the Holy Prophet) called him and said: Verily my father and your father are in the Fire.
