Messenger of Allah ﷺ 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." Messenger of Allah 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.
