How could a woman (Safiyya bint Huyayy), whose father, brother, and husband were killed by Muhammad's army, be seen at the end of the day on the same bed with their killer?

Safiyyah bint Huyayy, may Allah be pleased with her, was graced by Islam and became a wife of the Prophet Muhammad, peace and blessings be upon him, and a Mother of the Believers. The Prophet married her after her waiting period ended and she declared her Islam, having freed her and made her manumission her dowry, and he held a wedding feast. Safiyyah had seen a dream that she would marry the Prophet, peace and blessings be upon him, and Allah granted her immense honor, for she was the daughter of a prophet, her paternal uncle was a prophet, and her husband was a prophet. This marriage refuted the suspicions raised by the disbelievers, clarifying that the Prophet, peace and blessings be upon him, did not consummate the marriage with her until after she embraced Islam and any hatred in her heart dissipated.
