Musnad Ahmad 554:0

Narrated Ma’qil ibn Abi Ma’qil: The Messenger of Allah (ﷺ) said: "Whoever interferes in the lineage of a people, bringing into them someone who does not belong to them, then he has no share with Allah, and Allah will not admit him into His Paradise." And whoever denies his child while he recognizes him, Allah will veil Himself from him and will disgrace him before the first and the last on the Day of Resurrection.
