Sunan of Abu Dawood Book 1, Hadith 314

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، أَخْبَرَنَا سَلاَّمُ بْنُ سُلَيْمٍ، عَنْ إِبْرَاهِيمَ بْنِ مُهَاجِرٍ، عَنْ صَفِيَّةَ بِنْتِ شَيْبَةَ، عَنْ عَائِشَةَ، قَالَتْ دَخَلَتْ أَسْمَاءُ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَتْ يَا رَسُولَ اللَّهِ كَيْفَ تَغْتَسِلُ إِحْدَانَا إِذَا طَهُرَتْ مِنَ الْمَحِيضِ قَالَ ‏ "‏ تَأْخُذُ سِدْرَهَا وَمَاءَهَا فَتَوَضَّأُ ثُمَّ تَغْسِلُ رَأْسَهَا وَتَدْلُكُهُ حَتَّى يَبْلُغَ الْمَاءُ أُصُولَ شَعْرِهَا ثُمَّ تُفِيضُ عَلَى جَسَدِهَا ثُمَّ تَأْخُذُ فِرْصَتَهَا فَتَطَّهَّرُ بِهَا ‏"‏ ‏.‏ قَالَتْ يَا رَسُولَ اللَّهِ كَيْفَ أَتَطَهَّرُ بِهَا قَالَتْ عَائِشَةُ فَعَرَفْتُ الَّذِي يَكْنِي عَنْهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقُلْتُ لَهَا تَتَّبِعِينَ بِهَا آثَارَ الدَّمِ ‏.‏
