Sunan an-Nasa'i, Volume 4, Book 26, Hadith 3332 (DarusSalam) ⓘ

It was narrated that 'Uqbah bin Al-Harith said: I married a woman, then a black woman came to us and said: I breast-fed you both. I went to the Prophet and said: I married so and so and a black woman came to me and said: I breast-fed you both. He turned away from me so I came to him from the other side and said: She is lying. He said: "How can you be intimate with your wife when she says that she breast-fed you both? Leave her (divorce her)."
