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.
Sahih al-Bukhari Book 12, Hadith 6
