حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدٍ حَدَّثَنَا الْمُحَارِبِيُّ عَنْ سَلَّامِ بْنِ سُلَيْمٍ أَوْ سَلْمٍ شَکَّ أَبُو الْحَسَنِ وَأَظُنُّهُ هُوَ أَبُو الْأَحْوَصِ عَنْ حُمَيْدٍ عَنْ أَنَسٍ قَالَ کَانَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ وَقَّتَ لِلنُّفَسَائِ أَرْبَعِينَ يَوْمًا إِلَّا أَنْ تَرَی الطُّهْرَ قَبْلَ ذَلِکَ
