Sahih al-Bukhari 3281

Narrated Safiya bint Huyay:

While Allah's Messenger (ﷺ) was in I`tikaf, I called on him at night and having had a talk with him, I got up to depart. He got up also to accompany me to my dwelling place, which was then in the house of Usama bin Zaid. Two Ansari men passed by, and when they saw the Prophet (ﷺ) they hastened away. The Prophet said (to them). "Don't hurry! It is Safiya, the daughter of Huyay (i.e. my wife)." They said, "Glorified be Allah! O Allah's Messenger (ﷺ)! (How dare we suspect you?)" He said, "Satan circulates in the human mind as blood circulates in it, and I was afraid that Satan might throw an evil thought (or something) into your hearts."

حَدَّثَنِي مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ عَلِيِّ بْنِ حُسَيْنٍ، عَنْ صَفِيَّةَ ابْنَةِ حُيَىٍّ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم مُعْتَكِفًا، فَأَتَيْتُهُ أَزُورُهُ لَيْلاً فَحَدَّثْتُهُ ثُمَّ قُمْتُ، 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 ‏"‏‏.‏ فَقَالاَ سُبْحَانَ اللَّهِ يَا رَسُولَ اللَّهِ‏.‏ قَالَ ‏"‏ إِنَّ الشَّيْطَانَ يَجْرِي مِنَ الإِنْسَانِ مَجْرَى الدَّمِ، وَإِنِّي خَشِيتُ أَنْ يَقْذِفَ فِي قُلُوبِكُمَا سُوءًا ـ أَوْ قَالَ ـ شَيْئًا ‏"‏‏.‏
