Mukhtasar Muslim (Abridged) 878 — Suckling once or twice

Lady Umm Fadl (may Allah be pleased with her) says that a man from a village came to the Messenger of Allah (peace and blessings be upon him) while he was in my house. He said, "O Prophet of Allah! I had a wife and I married another woman. My first wife claims that she suckled the second woman once or twice." The Messenger of Allah (peace and blessings be upon him) said, "Prohibition is not established by suckling once or twice."
