I heard the Prophet ﷺ saying, "Whoever claims to be the son of a person other than his father, and he knows that person is not his father, then Paradise will be forbidden for him." I mentioned that to Abu Bakra, and he said, "My ears heard that and my heart memorized it from Messenger of Allah ﷺ.  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ مَنِ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهْوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ فَذَكَرْتُهُ لأَبِي بَكْرَةَ فَقَالَ وَأَنَا سَمِعَتْهُ أُذُنَاىَ وَوَعَاهُ قَلْبِي مِنْ رَسُولِ اللَّهِ ﷺ  

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.  

عَنْ سَعْدٍ وَأَبِي بَكْرَةَ كِلاَهُمَا يَقُولُ سَمِعَتْهُ أُذُنَاىَ وَوَعَاهُ قَلْبِي مُحَمَّدًا ﷺ يَقُولُ مَنِ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهُوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ  

“I heard Sa'd and Abu Bakrah both say that they heard directly from Muhammad ﷺ saying it and memorized: 'Whoever claims to belong to someone other than his father knowing the he is not his father, Paradise will be forbidden to him.”  

سَمِعْتُ سَعْدًا وَأَبَا بَكْرَةَ وَكُلُّ وَاحِدٍ مِنْهُمَا يَقُولُ سَمِعَتْ أُذُنَاىَ وَوَعَى قَلْبِي مُحَمَّدًا ﷺ يَقُولُ مَنِ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهُوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ  

[Machine] The Messenger of Allah ﷺ said: "Whoever claims to belong to someone other than his father, knowing the truth, Paradise is forbidden for him."  

قَالَ رَسُولُ اللهِ ﷺ مَنِ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهُوَ يَعْلَمُ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ  

“I heard Sa'd and Abu Bakrah both say that they heard directly from Muhammad ﷺ saying it and memorized: 'Whoever claims to belong to someone other than his father knowing the he is not his father, Paradise will be forbidden to him.” (Using translation from Ibn Mājah 2610)   

أَنَّ مَنْ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهُوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ قَالَ فَلَقِيتُ أَبَا بَكْرَةَ فَحَدَّثْتُهُ فَقَالَ وَأَنَا سَمِعَتْ أُذُنَايَ وَوَعَى قَلْبِي مِنْ مُحَمَّدٍ ﷺ  

[Machine] The Messenger of Allah ﷺ said, "Whoever claims to belong to someone other than his/her own father, knowing that he/she is not his/her own father, then Paradise is forbidden for him/her."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنِ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهُوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ»  

"من ادُّعِى إِلَى غَير أَبِيه حَرَّم الله علَيهِ الْجَنَّة".
