حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، قَالَ حَدَّثَنِي حُمَيْدُ بْنُ نَافِعٍ، عَنْ زَيْنَبَ، عَنْ أُمِّ سَلَمَةَ ـ رضى الله عنها ـ أَنَّ امْرَأَةً تُوُفِّيَ زَوْجُهَا فَاشْتَكَتْ عَيْنَهَا، فَذَكَرُوهَا لِلنَّبِيِّ صلى الله عليه وسلم وَذَكَرُوا لَهُ الْكُحْلَ، وَأَنَّهُ يُخَافُ عَلَى عَيْنِهَا، فَقَالَ ‏ "‏ لَقَدْ كَانَتْ إِحْدَاكُنَّ تَمْكُثُ فِي بَيْتِهَا فِي شَرِّ أَحْلاَسِهَا ـ أَوْ فِي أَحْلاَسِهَا فِي شَرِّ بَيْتِهَا ـ فَإِذَا مَرَّ كَلْبٌ رَمَتْ بَعْرَةً، فَلاَ، أَرْبَعَةَ أَشْهُرٍ وَعَشْرًا ‏"‏‏.‏
