حَدَّثَنَا أَحْمَدُ بْنُ يُوسُفَ السُّلَمِيُّ، حَدَّثَنَا أَبُو عَاصِمٍ، عَنِ ابْنِ جُرَيْجٍ، عَنْ يَحْيَى بْنِ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ صَيْفِيٍّ، عَنْ عِكْرِمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أُمِّ سَلَمَةَ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ آلَى مِنْ بَعْضِ نِسَائِهِ شَهْرًا فَلَمَّا كَانَ تِسْعَةً وَعِشْرِينَ رَاحَ أَوْ غَدَا . فَقِيلَ يَا رَسُولَ اللَّهِ إِنَّمَا مَضَى تِسْعٌ وَعِشْرُونَ . فَقَالَ " الشَّهْرُ تِسْعٌ وَعِشْرُونَ " .
