Anas bin Malik said “Safiyyah first fell to Dihyat Al Kalbi, the she fell to the Apostle of Allaah(ﷺ).
Sunan Abi Dawud Book 20, Hadith 69
← Previous Hadith Anas bin Malik said “We came to Khaibar. We bestowed the conquest of fortress (on us), the beauty of Safiyyah daughter of Huyayy was mentioned to him (the Prophet). Her husband was killed (in the battle) and she was a bride. The Apostle of Allaah(ﷺ) chose her for himself. He came out with her till we reached Sadd Al Sahba’ where she was purified. So he cohabited with her.

Sunan Abi Dawud Book 20, Hadith 68 Next Hadith → Anas said “A beautiful slave girl fell to Dihyah”. The Apostle of Allaah(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.”
