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.
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عَفَّانُ، حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ رَجُلاً، قَالَ يَا رَسُولَ اللَّهِ أَيْنَ أَبِي قَالَ ‏"‏ فِي النَّارِ ‏"‏ ‏.‏ فَلَمَّا قَفَّى دَعَاهُ فَقَالَ ‏"‏ إِنَّ أَبِي وَأَبَاكَ فِي النَّارِ ‏"‏ ‏.‏
