Anas said “A beautiful slave girl fell to Dihyah”. The Messenger of Allah(ﷺ) purchased her for seven slaves. He then gave her to Umm Sulaim for decorating her and preparing her for marriage. The narrator Hammad said, I think he said “Safiyyah daughter of Huyayy should pass her waiting period in her (Umm Sulaims’) house.”
