حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، وَعَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، قَالاَ حَدَّثَنَا سُفْيَانُ، عَنْ عَلِيِّ بْنِ الأَقْمَرِ، عَنْ أَبِي حُذَيْفَةَ، وَكَانَ، مِنْ أَصْحَابِ ابْنِ مَسْعُودٍ عَنْ عَائِشَةَ، قَالَتْ حَكَيْتُ لِلنَّبِيِّ صلى الله عليه وسلم رَجُلاً فَقَالَ ‏"‏ مَا يَسُرُّنِي أَنِّي حَكَيْتُ رَجُلاً وَأَنَّ لِي كَذَا وَكَذَا ‏"‏ ‏.‏ قَالَتْ فَقُلْتُ يَا رَسُولَ اللَّهِ إِنَّ صَفِيَّةَ امْرَأَةٌ وَقَالَتْ بِيَدِهَا هَكَذَا كَأَنَّهَا تَعْنِي قَصِيرَةً ‏.‏ فَقَالَ ‏"‏ لَقَدْ مَزَجْتِ بِكَلِمَةٍ لَوْ مَزَجْتِ بِهَا مَاءَ الْبَحْرِ لَمُزِجَ ‏"‏ ‏.‏
