It is narrated from the wife of the Messenger, Sayyida Safiyyah bint Huyayy (may Allah be pleased with her), she says: The Messenger of Allah (peace and blessings be upon him) was in i'tikaf. I came to meet him at night, spoke with him, and then when I got up to return, the Messenger of Allah (peace and blessings be upon him) stood up with me to escort me back. Her residence was in that place which later became the house of Sayyiduna Usamah bin Zaid (may Allah be pleased with him). Meanwhile, two Ansari men passed by. When they saw the Prophet (peace and blessings be upon him), they hurried by, but the Prophet (peace and blessings be upon him) said to them: "Wait (and walk as you were walking before), this woman is my wife Safiyyah bint Huyayy (may Allah be pleased with her)." They said: "Glory be to Allah! (How astonishing) O Messenger of Allah! (What need is there for this clarification?)" The Prophet (peace and blessings be upon him) said: "Satan circulates in the human body like blood, so I feared that he might cast some evil thought into your hearts."
