Narrated Anas bin Malik:

We arrived at Khaibar, and when Allah helped His Apostle to open the fort, the beauty of Safiya bint Huyai bin Akhtaq whose husband had been killed while she was a bride, was mentioned to Allah's Apostle. The Prophet selected her for himself, and set out with her, and when we reached a place called Sidd-as-Sahba,' Safiya became clean from her menses then Allah's Apostle married her. Hais (i.e. an 'Arabian dish) was prepared on a small leather mat. Then the Prophet ﷺ said to me, "I invite the people around you." So that was the marriage banquet of the Prophet and Safiya. Then we proceeded towards Medina, and I saw the Prophet, making for her a kind of cushion with his cloak behind him (on his camel). He then sat beside his camel and put his knee for Safiya to put her foot on, in order to ride (on the camel).

حَدَّثَنَا عَبْدُ الْغَفَّارِ بْنُ دَاوُدَ، حَدَّثَنَا يَعْقُوبُ بْنُ عَبْدِ الرَّحْمَنِ، ح وَحَدَّثَنِي أَحْمَدُ، حَدَّثَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي يَعْقُوبُ بْنُ عَبْدِ الرَّحْمَنِ الزُّهْرِيُّ، عَنْ عَمْرٍو، مَوْلَى الْمُطَّلِبِ عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ قَدِمْنَا خَيْبَرَ، فَلَمَّا فَتَحَ اللَّهُ عَلَيْهِ الْحِصْنَ ذُكِرَ لَهُ جَمَالُ صَفِيَّةَ بِنْتِ حُيَىِّ بْنِ أَخْطَبَ، وَقَدْ قُتِلَ زَوْجُهَا وَكَانَتْ عَرُوسًا، فَاصْطَفَاهَا النَّبِيُّ ﷺ لِنَفْسِهِ، فَخَرَجَ بِهَا، حَتَّى بَلَغْنَا سَدَّ الصَّهْبَاءِ حَلَّتْ، فَبَنَى بِهَا رَسُولُ اللَّهِ ﷺ، ثُمَّ صَنَعَ حَيْسًا فِي نِطَعٍ صَغِيرٍ، ثُمَّ قَالَ لِي " آذِنْ مَنْ حَوْلَكَ ". فَكَانَتْ تِلْكَ وَلِيمَتَهُ عَلَى صَفِيَّةَ، ثُمَّ خَرَجْنَا إِلَى الْمَدِينَةِ، فَرَأَيْتُ النَّبِيَّ ﷺ يُحَوِّي لَهَا وَرَاءَهُ بِعَبَاءَةٍ، ثُمَّ يَجْلِسُ عِنْدَ بَعِيرِهِ، فَيَضَعُ رُكْبَتَهُ، وَتَضَعُ صَفِيَّةُ رِجْلَهَا عَلَى رُكْبَتِهِ حَتَّى تَرْكَبَ.
