Anas bin Malik reported,

The Messenger of Allah ﷺ set out on a military expedition, and we prayed the dawn prayer near Khaybar in the darkness before sunrise. Then the Prophet of Allah ﷺ mounted his horse, Abu Talha mounted his, and I rode behind Abu Talha. The Prophet of Allah ﷺ urged his mount through the alleyways of Khaybar, and my knee was touching the thigh of the Prophet of Allah ﷺ. His lower garment slipped back from his thigh, so much so that I could see the whiteness of the thigh of the Prophet of Allah ﷺ. When he entered the town, he said, "Allah is the Greatest. Khaybar is destroyed. When we descend upon the territory of a people, then evil is the morning of those who have been warned." He repeated this three times.The people had gone out to their daily work, and they cried, "Muhammad!"Abdul-Aziz said, and some of our companions added, "And the army," meaning the troops.We took the town by force. The captives were gathered together, and Dihya came and said, "Prophet of Allah, give me a slave-girl from the captives."He said, "Go and take a slave-girl."So he took Safiya bint Huyayy. Then a man came to the Prophet ﷺ and said, "Prophet of Allah, you have given Dihya Safiya bint Huyayy, the noblewoman of Qurayza and Nadir? She is fitting for none but you."He said, "Call him to bring her."He brought her, and when the Prophet ﷺ looked at her, he said to Dihya, "Take a different slave-girl from the captives."The Prophet ﷺ then freed her and married her.Thabit asked him, "Abu Hamza, what dowry did he give her?"He replied, "Her own self. He freed her and married her."When they were on the road, Umm Sulaym prepared her for him and brought her to him as a bride that night. So the Prophet ﷺ awoke a bridegroom, and he said, "Whoever has anything, let him bring it." A leather mat was spread out, and one man came with dried curd, another with dates, and another with clarified butter. I think he also mentioned parched barley. They mixed it together into a dish called hays, and that was the wedding feast of the Messenger of Allah ﷺ.

عن أنس

أن رسول الله ﷺ غزا، فصلينا عندها صلاة الغداة بغلس، فركب نبي الله ﷺ وركب أبو طلحة، وأنا رديف أبي طلحة، فأجرى نبي الله ﷺ في زقاق خيبر، وإن ركبتي لتمس فخذ نبي الله ﷺ، ثم حسر الإزار عن فخذه، حتى إني أنظر إلى بياض فخذ نبي الله ﷺ، فلما دخل القرية قال: الله أكبر خربت خيبر، إنا إذا نزلنا بساحة قوم، فساء صباح المنذرين قالها ثلاثا، قال: وخرج القوم إلى أعمالهم، فقالوا: محمد- قال عبد العزيز، وقال بعض أصحابنا: والخميس، يعني الجيش- فأصبناها عنوة، فجمع السبي، فجاء دحية، فقال: يا نبي الله، أعطني جارية من السبي، قال: اذهب فخذ جارية فأخذ صفية بنت حيي، فجاء رجل إلى النبي ﷺ فقال: يا نبي الله، أعطيت دحية صفية بنت حيي، سيدة قريظة والنضير؟ لا تصلح إلا لك، قال: ادعوه بها فجاء بها، فلما نظر إليها النبي ﷺ قال: خذ جارية من السبي غيرها قال: فأعتقها النبي ﷺ وتزوجها. فقال له ثابت: يا أبا حمزة، ما أصدقها؟ قال: نفسها، أعتقها، وتزوجها، حتى إذا كان بالطريق جهزتها له أم سليم، فأهدتها له من الليل، فأصبح النبي ﷺ عروسا فقال: من كان عنده شيء فليجيء به وبسط نطعا، فجعل الرجل يجيء بالأقط، وجعل الرجل يجيء بالتمر، وجعل الرجل يجيء بالسمن، قال: وأحسبه قد ذكر السويق قال: فحاسوا حيسا، فكانت وليمة رسول الله ﷺ.
