Wathilah bin al-Asqa' (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "A woman takes three inheritances: that of her foundling, of the slave she freed, and of her child over whom she undertook li'an (mutual imprecation)."
This is not established.
