It is narrated from Hazrat Safiyyah that once the Prophet (peace be upon him) was in a state of i'tikaf. I came to the Prophet's presence at night to meet him. After talking for a while, I stood up to leave, and the Prophet (peace be upon him) also got up to see me off. At that time, my residence was in the house of Usama bin Zaid. Meanwhile, two Ansari men passed by, and when they saw the Prophet (peace be upon him), they quickened their pace. The Prophet (peace be upon him) said to them, "Wait, this is Safiyyah bint Huyayy." Both of them said, "Subhan Allah, O Messenger of Allah (could we ever think anything bad about you?)" The Prophet (peace be upon him) said, "Satan runs in the human being like blood, so I feared that he might put some evil thought into your hearts."
