Musannaf Ibn Abi Shayba 20:26

Abu Bakr narrated to us, he said: Yazid bin Harun narrated to us, he said: Abbad bin Mansur narrated to us, from Ikrimah, from Ibn Abbas, who said: The Messenger of Allah (may Allah bless him and grant him peace) separated between them—meaning the two who performed *li’an* (mutual cursing)—and he decreed that she has no housing from him, nor maintenance, because they are separated without divorce and without the husband having passed away. And he decreed that the child shall not be attributed to a father, and she shall not be accused (of adultery), and her child shall not be accused. Whoever accuses her or accuses her child, then upon him is the prescribed punishment (*hadd*).
