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

[AI] My ears heard it and my heart retained it from Muhammad ﷺ that "Whoever claims a father other than his own father, while knowing that he is not his father, Paradise is forbidden to him." He said: I met Abu Bakra, and I told him about it, and he said: My ears also heard it and my heart retained it from Muhammad ﷺ.

سَمِعَتْهُ أُذُنَايَ وَوَعَاهُ قَلْبِي مِنْ مُحَمَّدٍ ﷺ أَنَّهُ «مَنِ ادَّعَى أَبًا غَيْرَ أَبِيهِ وَهُوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ، فَالْجَنَّةُ عَلَيْهِ حَرَامٌ». قَالَ: فَلَقِيتُ أَبَا بَكْرَةَ، فَحَدَّثْتُهُ، فَقَالَ: وَأَنَا سَمِعَتْهُ أُذُنَايَ وَوَعَاهُ قَلْبِي مِنْ مُحَمَّدٍ ﷺ.

[Machine] "This is the branch of the first person who threw an arrow in the way of Allah, and this is the rope of the fortress of Taif to the Messenger of Allah ﷺ. Indeed, they both mentioned that the Messenger of Allah ﷺ said, 'Whoever claims to belong to someone other than his father, knowing that he is not his father, Paradise is forbidden for him.'"

شُعْبَةُ هَذَا أَوَّلُ مَنْ رَمَى بِسَهْمٍ فِي سَبِيلِ اللَّهِ وَهَذَا تَدَلَّى حِصْنِ الطَّائِفِ إِلَى رَسُولِ اللَّهِ ﷺ إِنَّهُمَا حَدَّثَا أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «مَنِ ادَّعَى إِلَى غَيْرِ أَبِيهِ وَهُوَ يَعْلَمُ أَنَّهُ غَيْرُ أَبِيهِ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ»

اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنَ ادَّعَى إِلَى غَيْرِ أَبِيهِ أَحْسَبُهُ قَالَ وَانْتَمَى إِلَى غَيْرِ مَوَالِيهِ فَالْجَنَّةُ عَلَيْهِ حَرَامٌ
