Safiyyah said :

The Messenger of Allah (ﷺ) was in the I’TIKAF(seclusion in the mosque). I came to visit him at night . I talked to him, got up and turned my back. He got up with me to accompany me. He was living in the house of Usamah b. Zaid. Two men of the Ansar passed by him. When they saw the Messenger of Allah (ﷺ), they walked quickly. The prophet (ﷺ) said: Be at ease; she is Safiyyah daughter of Huyayy. They said: Glory be to Allah, Messenger of Allah! He said: The devil flows in man as the blood flows in him. I feared that he might inject something in your hearts, or he said “evil” (instead of something).

حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ الْمَرْوَزِيُّ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عَلِيِّ بْنِ حُسَيْنٍ، عَنْ صَفِيَّةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم مُعْتَكِفًا فَأَتَيْتُهُ أَزُورُهُ لَيْلاً فَحَدَّثْتُهُ وَقُمْتُ فَانْقَلَبْتُ فَقَامَ مَعِي لِيَقْلِبَنِي - وَكَانَ مَسْكَنُهَا فِي دَارِ أُسَامَةَ بْنِ زَيْدٍ - فَمَرَّ رَجُلاَنِ مِنَ الأَنْصَارِ فَلَمَّا رَأَيَا النَّبِيَّ صلى الله عليه وسلم أَسْرَعَا فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ عَلَى رِسْلِكُمَا إِنَّهَا صَفِيَّةُ بِنْتُ حُيَىٍّ ‏"‏ ‏.‏ قَالاَ سُبْحَانَ اللَّهِ يَا رَسُولَ اللَّهِ قَالَ ‏"‏ إِنَّ الشَّيْطَانَ يَجْرِي مِنَ الإِنْسَانِ مَجْرَى الدَّمِ فَخَشِيتُ أَنْ يَقْذِفَ فِي قُلُوبِكُمَا شَيْئًا ‏"‏ ‏.‏ أَوْ قَالَ ‏"‏ شَرًّا ‏"‏ ‏.‏
