The wives of the Prophet ﷺ were with him in the mosque (while he was in Iʿtikaf) and then they departed and the Prophet ﷺ said to Safiya bint Huyai, "Don't hurry up, for I shall accompany you," (and her dwelling was in the house of Usama). The Prophet ﷺ went out and in the meantime two Ansari men met him and they looked at the Prophet ﷺ and passed by. The Prophet ﷺ said to them, "Come here. She is (my wife) Safiya bint Huyai." They replied, "Subhan Allah, (How dare we think of evil) O Allah's Apostle! (we never expect anything bad from you)." The Prophet ﷺ replied, "Satan circulates in the human being as blood circulates in the body, and I was afraid lest Satan might insert an evil thought in your minds."  

أَنَّ صَفِيَّةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهُ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ حَدَّثَنَا هِشَامٌ أَخْبَرَنَا مَعْمَرٌ عَنِ الزُّهْرِيِّ عَنْ عَلِيِّ بْنِ الْحُسَيْنِ كَانَ النَّبِيُّ ﷺ فِي الْمَسْجِدِ وَعِنْدَهُ أَزْوَاجُهُ فَرُحْنَ فَقَالَ لِصَفِيَّةَ بِنْتِ حُيَىٍّ لاَ تَعْجَلِي حَتَّى أَنْصَرِفَ مَعَكِ وَكَانَ بَيْتُهَا فِي دَارِ أُسَامَةَ فَخَرَجَ النَّبِيُّ ﷺ مَعَهَا فَلَقِيَهُ رَجُلاَنِ مِنَ الأَنْصَارِ فَنَظَرَا إِلَى النَّبِيِّ ﷺ ثُمَّ أَجَازَا وَقَالَ لَهُمَا النَّبِيُّ ﷺ تَعَالَيَا إِنَّهَا صَفِيَّةُ بِنْتُ حُيَىٍّ قَالاَ سُبْحَانَ اللَّهِ يَا رَسُولَ اللَّهِ قَالَ إِنَّ الشَّيْطَانَ يَجْرِي مِنَ الإِنْسَانِ مَجْرَى الدَّمِ وَإِنِّي خَشِيتُ أَنْ يُلْقِيَ فِي أَنْفُسِكُمَا شَيْئًا
