"The Messenger of Allah invaded Khaibar and we prayed Al-Ghadah (Fajr) there (early in the morning) when it was still dark. Then the Prophet rode and Abu Talha rode, and I was riding behind Abu Talha. The Prophet of Allah passed through the lane of Khaibar quickly, and my knee was touching the thigh of the Messenger of Allah, and I could see the whiteness of the thigh of the Prophet. When he entered the town he said: 'Allahu Akbar, Khaibar is destroyed! Whenever we approach a (hostile) nation to fight, evil will be the morning for those who have been warned.' He said this three times. The people came out for their work." (One of the narrators) 'Abdul-'Aziz said: "They said: 'Muhammad (has come)!'" 'Abdul-'Aziz said: "Some of our companions said: 'With his army.'" "We conquered Khaibar and gathered the captives. Dihyah came and said: 'O Prophet of Allah, give me a slave girl from among the captives.' He said: 'Go and take a slave girl.' He took Safiyyah bint Huyayy. Then a man came to the Prophet and said: 'O Messenger of Allah, you gave Dihyah Safiyyah bint Huyayy, and she is the chief mistress of Quraizah and An-Nadir, and she is fit for no one but you.' He said: 'Call him to bring her.' When the Prophet saw her, he said: 'Take any other slave girl from among the captives.'" He said: "The Prophet of Allah set her free and married her." (One of the narrators) Thabit said to him: "O Abu Hamzah, what dowry did he give her?" He (Anas) said: "Herself; he set her free and married her." He said: "While on the road, Umm Sulaim fitted her out and presented her to him in the night, and the following morning he was a bridegroom. He said: 'Whoever has anything, let him bring it.' He spread out a leather cloth and men came with cottage cheese, dates, and ghee, and they made Hais, and that was the Walimah (wedding feast) of the Messenger of Allah."

أَنَّ رَسُولَ اللهِ ﷺ غَزَا خَيْبَرَ فَصَلَّيْنَا عِنْدَهَا صَلَاةَ الْغَدَاةِ بِغَلَسٍ فَرَكِبَ نَبِيُّ اللهِ ﷺ وَرَكِبَ أَبُو طَلْحَةَ وَأنا رَدِيفُ أَبِي طَلْحَةَ فَأَخَذَ نَبِيُّ اللهِ ﷺ فِي آفَاقِ خَيْبَرَ وَإِنِّي لَأَرَى بَيَاضَ فَخِذِ نَبِيِّ اللهِ ﷺ فَلَمَّا دَخَلَ الْقَرْيَةَ قَالَ اللهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ قَالَهَا ثَلَاثَ مِرَارٍ قَالَ وَخَرَجَ الْقَوْمُ إِلَى أَعْمَالِهِمْ قَالَ عَبْدُ الْعَزِيزِ فَقَالُوا مُحَمَّدٌ قَالَ عَبْدُ الْعَزِيزِ وَقَالَ بَعْضُ أَصْحَابِنَا وَالْخَمِيسُ فَأَصَبْنَاهَا عَنْوَةً فَجُمِعَ السَّبْيُ فَجَاءَ دِحْيَةُ فَقَالَ يَا نَبِيَّ اللهِ أَعْطِنِي جَارِيَةً مِنَ السَّبْيِ قَالَ اذْهَبْ فَخُذْ جَارِيَةً فَأَخَذَ صَفِيَّةَ بِنْتَ حُيَيٍّ فَجَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ يَا نَبِيَّ اللهِ أَعْطَيْتَ دِحْيَةَ صَفِيَّةَ بِنْتَ حُيَيٍّ سَيِّدَةَ قُرَيْظَةَ وَالنَّضِيرِ مَا تَصْلُحُ إِلَّا لَكَ قَالَ «فَادْعُوهُ بِهَا» فَجَاءَ بِهَا فَلَمَّا نَظَرَ إِلَيْهَا النَّبِيُّ ﷺ قَالَ «خُذْ جَارِيَةً مِنَ السَّبْيِ غَيْرَهَا» قَالَ وَإِنَّ النَّبِيَّ ﷺ أَعْتَقَهَا وَتَزَوَّجَهَا حَتَّى إِذَا كَانَ بِالطَّرِيقِ جَهَّزَتْهَا لَهُ أُمُّ سُلَيْمٍ وَأَهْدَتْهَا لَهُ مِنَ اللَّيْلِ فَأَصْبَحَ النَّبِيُّ ﷺ عَرُوسًا قَالَ «مَنْ كَانَ عِنْدَهُ شَيْءٌ فَلْيَجِئْ بِهِ» وَبَسَطَ نِطَعًا فَجَعَلَ الرَّجُلُ يَجِيءُ بِالْأَقِطِ وَجَعَلَ يَجِيءُ بِالتَّمْرِ وَجَعَلَ الرَّجُلُ يَجِيءُ بِالسَّمْنِ فَحَاسُوا حَيْسَةً فَكَانَتْ وَلِيمَةَ رَسُولِ اللهِ ﷺ  

"The Messenger of Allah stayed with Safiyyah bint Huyayy bin Akhtab on the way (back from) Khaibar for three days when he married her, then she was among those who were commanded to observe Hijab." (Using translation from Nasāʾī 3381)  

أَنَّهُ سَمِعَ أَنَسًا يَقُولُ إِنَّ رَسُولَ اللهِ ﷺ «أَقَامَ عَلَى صَفِيَّةَ بِنْتِ حُيَيِّ بْنِ أَخْطَبَ بِطَرِيقِ خَيْبَرَ ثَلَاثَةَ أَيَّامٍ حِينَ أَعْرَسَ بِهَا ثُمَّ كَانَتْ فِيمَنْ ضُرِبَ عَلَيْهَا»
