85/29. Chapter:
Whoever claims to be the son of a person other than his father
Sahih Bukhari
حَدَّثَنَا أَصْبَغُ بْنُ الْفَرَجِ، حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي عَمْرٌو، عَنْ جَعْفَرِ بْنِ رَبِيعَةَ، عَنْ عِرَاكٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لاَ تَرْغَبُوا عَنْ آبَائِكُمْ، فَمَنْ رَغِبَ عَنْ أَبِيهِ فَهُوَ كُفْرٌ ".
Narrated Abu Huraira: The Prophet (ﷺ) said, "Do not deny your fathers (i.e. claim to be the sons of persons other than your fathers), and whoever denies his father, is charged with disbelief."
