The Book of the Prohibited actions
Prohibition of attributing wrong Fatherhood
عَنْ سَعْدِ بْنِ أَبِي وَقَّاصٍ رَضِيَ اللَّه عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: مَنْ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهْوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ، فَالْجَنَّةُ عَلَيْهِ حَرَامٌ ((مُتَّفَقٌ عَلَيْهِ)).
Sa'd bin Abu Waqqas (May Allah be pleased with him) said: The Prophet (ﷺ) said, "He who (falsely) attributes his fatherhood to anyone besides his real father, knowing that he is not his father, will be forbidden to enter Jannah." [Al-Bukhari and Muslim].
