Sahih al-Bukhari 947
Narrated Anas bin Malik:
Allah's Messenger (ﷺ) (p.b.u.h) offered the Fajr prayer when it was still dark, then he rode and said, 'Allah 
Akbar! Khaibar is ruined. When we approach near to a nation, the most unfortunate is the morning of 
those who have been warned." The people came out into the streets saying, "Muhammad and his 
army." Allah's Messenger (ﷺ) vanquished them by force and their warriors were killed; the children and 
women were taken as captives. Safiya was taken by Dihya Al-Kalbi and later she belonged to Allah's 
Apostle go who married her and her Mahr was her manumission.
حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، وَثَابِتٍ الْبُنَانِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى الصُّبْحَ بِغَلَسٍ ثُمَّ رَكِبَ فَقَالَ ‏
"‏ اللَّهُ أَكْبَرُ خَرِبَتْ خَيْبَرُ، إِنَّا إِذَا نَزَلْنَا بِسَاحَةِ قَوْمٍ فَسَاءَ صَبَاحُ الْمُنْذَرِينَ ‏"‏‏.‏ فَخَرَجُوا يَسْعَوْنَ فِي السِّكَكِ وَيَقُولُونَ مُحَمَّدٌ وَالْخَمِيسُ ـ قَالَ وَالْخَمِيسُ الْجَيْشُ ـ فَظَهَرَ عَلَيْهِمْ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَتَلَ الْمُقَاتِلَةَ وَسَبَى الذَّرَارِيَّ، فَصَارَتْ صَفِيَّةُ لِدِحْيَةَ الْكَلْبِيِّ، وَصَارَتْ لِرَسُولِ اللَّهِ صلى الله عليه وسلم ثُمَّ تَزَوَّجَهَا وَجَعَلَ صَدَاقَهَا عِتْقَهَا‏.‏ فَقَالَ عَبْدُ الْعَزِيزِ لِثَابِتٍ يَا أَبَا مُحَمَّدٍ، أَنْتَ سَأَلْتَ أَنَسًا مَا أَمْهَرَهَا قَالَ أَمْهَرَهَا نَفْسَهَا‏.‏ فَتَبَسَّمَ‏.‏
