Sayyidah Safiyyah bint Huyayy (may Allah be pleased with her) narrates: The Messenger of Allah (peace and blessings be upon him) was in i'tikaf (spiritual retreat), so I came to him (peace and blessings be upon him) at night in the mosque and talked with him (peace and blessings be upon him). Then I stood up, and he (peace and blessings be upon him) also stood up with me in order to accompany me back, and her dwelling was in the house of Usamah bin Zayd (may Allah be pleased with him). Two Companions from the Ansar passed by, and when they saw the Prophet (peace and blessings be upon him), they walked on quickly. So the Prophet (peace and blessings be upon him) said: "Wait, this is Safiyyah bint Huyayy." They said: Subhan Allah (Glory be to Allah), O Messenger of Allah! So he (peace and blessings be upon him) said: "Satan flows in the son of Adam like blood, and I feared that he might cast some whispering into your hearts," or he said: "something evil."
