[Machine] The Messenger of Allah ﷺ said: "Whoever claims to have a father other than his biological father, or supports those who have set him free but are not his guardians, he is under the curse of Allah, the angels, and all people, and their repentance will not be accepted from him until the Day of Resurrection. No compensation or justice will be taken from him."  

قَالَ رَسُولُ اللهِ ﷺ أَيُّمَا رَجُلٍ ادَّعَى إِلَى غَيْرِ وَالِدِهِ أَوْ تَوَلَّى غَيْرَ مَوَالِيهِ الَّذِينَ أَعْتَقُوهُ فَإِنَّ عَلَيْهِ لَعْنَةَ اللهِ وَالْمَلائِكَةِ وَالنَّاسِ أَجْمَعِينَ إِلَى يَوْمِ الْقِيَامَةِ لَا يُقْبَلُ مِنْهُ صَرْفٌ وَلا عَدْلٌ  

if a man becomes the client of any people without the permission of his patrons (i.e. those who have freed him), on him will be the curse of Allah, of angels and of all people; no obligatory or supererogatory worship will be accepted from him. (Using translation from Abū Dāʾūd 5114)   

وَقَالَ مَنْ تَوَلَّى قَوْمًا بِغَيْرِ إِذْنِ مَوَالِيهِ فَعَلَيْهِ لَعْنَةُ اللهِوَالْمَلَائِكَةِ لَا يَقْبَلُ اللهُ مِنْهُ صَرْفًا وَلَا عَدْلًا  

[Machine] The Messenger of Allah ﷺ said: "Whoever claims to have a relationship with someone other than his biological father, or supports those who are not his legal guardians, those who have freed him from slavery, then upon him is the curse of Allah, the angels, and all people, until the Day of Judgment. His expenditures and testimonies will not be accepted."  

قَالَ رَسُولُ اللَّهِ ﷺ «أَيُّمَا رَجُلٍ ادَّعَى إِلَى غَيْرِ وَالِدِهِ أَوْ تَوَلَّى غَيْرَ مَوَالِيهِ الَّذِينَ أَعْتَقُوهُ فَإِنَّ عَلَيْهِ لَعْنَةَ اللَّهِ وَالْمَلَائِكَةِ وَالنَّاسِ أَجْمَعِينَ إِلَى يَوْمِ الْقِيَامَةِ لَا يُقْبَلُ مِنْهُ صَرْفٌ وَلَا عَدْلٌ»  

"أَيُّمَا رجل ادعى غَيرَ وَالِدِهِ، أوْ غَير مَوْاليهِ الذينَ أعْتَقُوهُ فَإِنَّ عَلَيهِ لَعْنَةَ اللهِ والمَلائِكَةِ والناسِ أَجْمَعِينَ لَا يُقْبَلُ مِنْهُ صَرْفٌ وَلَا عدْلٌ".  

"مَنْ أَحْدَثَ حَدَثًا، أَوْ آوى مُحْدِثًا، أَوْ ادُّعِى إِلى غَيرِ أَبيه، أَوْ تَوَلَّى غَيرَ مَوَالِيهِ فَعَلَيه لَعْنَةُ اللهِ والْمَلائِكَة والنَّاس أَجمعين لَا يَقْبَلُ الله مِنْهُ يوم الْقِيَامَةِ صَرْفًا ولا عَدْلًا".
