Musnad Ahmad 830:93

Hushaym narrated to us, Khalid al-Hadhdha’ informed us, from Abu ‘Uthman, who said: When Ziyad was claimed [as a son by Mu’awiyah], I met Abu Bakrah and said: "What is this that you have done? For I heard Sa’d ibn Abi Waqqas saying: 'My two ears heard from the Messenger of Allah (ﷺ) while he was saying: "Whoever claims a father in Islam other than his own father, then Paradise is forbidden to him."'" Abu Bakrah said: "And I also heard it from the Messenger of Allah (ﷺ)."
