حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، قَالَ‏:‏ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ، قَالَ‏:‏ أَخْبَرَنَا ثَابِتٌ، عَنْ أَنَسٍ قَالَ‏:‏ بَيْنَمَا النَّبِيُّ صلى الله عليه وسلم مَعَ امْرَأَةٍ مِنْ نِسَائِهِ، إِذْ مَرَّ بِهِ رَجُلٌ، فَدَعَاهُ النَّبِيُّ صلى الله عليه وسلم فَقَالَ‏:‏ يَا فُلاَنُ، إِنَّ هَذِهِ زَوْجَتِي فُلاَنَةٌ، قَالَ‏:‏ مَنْ كُنْتُ أَظُنُّ بِهِ فَلَمْ أَكُنْ أَظُنُّ بِكَ، قَالَ‏:‏ إِنَّ الشَّيْطَانَ يَجْرِي مِنِ ابْنِ آدَمَ مَجْرَى الدَّمِ‏.‏

Anas said, "While the Prophet, may Allah bless him and grant him peace, was with one of his wives, a man passed by and the Prophet, may Allah bless him and grant him peace, called him and said, 'So-and-so, this is my wife so-and-so.' The man said, 'Whoever I might suspect, I would not suspect you!' The Prophet said, 'Shaytan flows in the son of Adam like blood flows.'"
