Sa'id bin Abi Sa'id · Divorce (Kitab Al-Talaq)

The words narrated by Malik alone are: "and he attributed the child to the woman." Yunus narrated from Al Zuhri on the authority of Sahl bin Sa’d in the tradition regarding li’an(invoking curses). He disowned her conception hence her child was attributed to her.

A bedouin came to the Prophet (ﷺ), and said: My wife has given birth to a black son, and I disown him. He then narrated the rest of the tradition to the same effect.

I can invoke the curse of Allah on anyone who wishes: The smaller surat an-Nisa (i.e. Surat at-Talaq) was revealed after the verse regarding the waiting period of four months and ten days had been revealed.
