'Uqbah bin al-Harith said: "I married Umm Yahya daughter of Abu Ihab. A black woman entered upon us. She said that she had suckled both of us. So I came to the Prophet (ﷺ), and amentioned it to him. He turned away from me. I said (to him): Messenger of Allah! she is a liar. He said: What do you know? She has said what she has said. Separate yourself from her (wife).
