Anas bin Malik reported,

I was riding behind Abu Talha on the day of Khaybar, and my foot was touching the foot of the Messenger of Allah ﷺ.We came upon them at sunrise. They had already led out their livestock and had gone out with their axes, baskets, and ropes. They cried out, "Muhammad! And the army!"The Messenger of Allah ﷺ said, "Khaybar is destroyed! When we descend upon the courtyard of a people, evil is the morning of those who have been warned."Allah defeated them. A beautiful young woman fell to Dihya as his share of the spoils, and the Messenger of Allah ﷺ purchased her in exchange for seven captives. He then handed her over to Umm Sulaym to prepare and groom her for him. (He said, and I think he said,) and to observe her waiting period in her house. She was Safiya bint Huyayy.The Messenger of Allah ﷺ made her wedding feast of dates, dried curd, and clarified butter. Hollows were dug in the ground, leather mats were brought and placed in them, and the dried curd and butter were brought, and the people ate their fill.The people said, "We do not know whether he has married her or taken her as a concubine." They said, "If he veils her, she is his wife. If he does not veil her, she is a concubine."When he was about to ride, he veiled her, and she sat on the rear of the camel, so they knew that he had married her.When they drew near Madinah, the Messenger of Allah ﷺ urged his mount forward, and we did the same. The she-camel Adba stumbled, and the Messenger of Allah was thrown off, and she was thrown off too. He stood up and shielded her from view. The women had looked out and said, "May Allah drive away the Jewish woman."I asked, "Abu Hamza, did the Messenger of Allah ﷺ really fall?"He replied, "Yes, by Allah, he did fall."

عن أنس قال

كنت ردف أبي طلحة يوم خيبر. و قدمي تمس قدم رسول الله ﷺ. قال: فأتيناهم حين بزغت الشمس. وقد أخرجوا مواشيهم وخرجوا بفؤوسهم ومكاتلهم ومرورهم. فقالوا: محمد، والخميس. قال: وقال رسول الله ﷺ: خربت خيبر! إنا إذا نزلنا بساحة قوم فساء صباح المنذرين قال: وهزمهم الله عز وجل. ووقعت في سهم دحية جارية جميلة. فاشتراها رسول الله ﷺ بسبعة أرؤس. ثم دفعها إلى أم سليم تصنعها له وتهيئها. (قال: وأحسبه قال:) وتعتد في بيتها. وهي صفية بنت حيي. قال: وجعل رسول الله ﷺ وليمتها التمر والأقط والسمن. فحصت الأرض أفاحيص. وجيء بالأنطاع. فوضعت فيها. وجيء بالأقط والسمن فشبع الناس. قال: وقال الناس: لا ندري أتزوجها أم اتخذها أم ولد. قالوا: إن حجبها فهي امرأته. وإن لم يحجبها فهي أم ولد. فلما أراد أن يركب حجبها. فقعدت على عجز البعير فعرفوا أنه قد تزوجها. فلما دنوا من المدينة دفع رسول الله ﷺ ودفعنا. قال: فعثرت الناقة العضباء. وندر رسول الله وندرت. فقام فسترها. وقد أشرفت النساء. فقلن: أبعد الله اليهودية. قال: قلت: يا أبا حمزة أوقع رسول الله ﷺ؟ قال: إي. والله! لقد وقع.
