Musannaf Ibn Abi Shayba 19:386

Abu Bakr narrated to us, he said: Yahya ibn Yaman narrated to us, from Sufyan, from Mutarrif and Jabir, from al-Sha'bi; and from Sufyan, from Layth, from Mujahid and 'Ata': They said: If the [punishment of] li'an (imprecation) is averted, the child is attributed to him.
