Musnad Ahmad 28:116

Wahb—meaning Ibn Jarir—narrated to us, Shu'bah narrated to us, from al-Hakam, from Mujahid, who said: A certain man wanted to be called [the son of] Junadah ibn Abi Umayyah. So Abdullah ibn Amr said: The Messenger of Allah (ﷺ) said: "Whoever claims [to be the son of] someone other than his father will not smell the fragrance of Paradise, even though its fragrance can be found from a distance of seventy years, or a journey of seventy years." He said: "And whoever lies about me intentionally, let him take his seat in the Fire."
