Musannaf Ibn Abi Shaybah 17136 — A man who sees his wife committing

Abdullah bin Shaddad said: I was once sitting with Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) by the well of Zamzam. A man came to him and said that he had forced his wife to abort her child, because the woman claimed that she had committed zina. Sayyiduna Ibn Abbas (may Allah be pleased with them both) said to him: You have done very badly if you yourself did the like of what she is confessing about herself. Then keep her as your wife; and if you did not do such a thing, let her go her way.
