Arabic hadith text
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَحْيَى بْنُ زَكَرِيَّاءَ بْنِ أَبِي زَائِدَةَ، وَأَبُو مُعَاوِيَةَ عَنْ عَاصِمٍ، عَنْ أَبِي عُثْمَانَ، عَنْ سَعْدٍ، وَأَبِي، بَكْرَةَ كِلاَهُمَا يَقُولُ سَمِعَتْهُ أُذُنَاىَ، وَوَعَاهُ، قَلْبِي مُحَمَّدًا صلى الله عليه وسلم يَقُولُ ‏"‏مَنِ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهُوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ ‏"
Translation
Sa'd and Abu Bakra each one of them said

My ears heard and my hearing preserved it that Muhammad (peace and blessings be upon him) observed: He who claimed for another one his fatherhood besides his own father knowingly that he was not his father-to him Paradise is forbidden.
