Bulugh al-Maram 143
The Book of Purification
Menstruation
وَعَنْ أُمِّ عَطِيَّةَ رَضِيَ اَللَّهُ عَنْهَا قَالَتْ: { كُنَّا لَا نَعُدُّ اَلْكُدْرَةَ وَالصُّفْرَةَ بَعْدَ اَلطُّهْرِ شَيْئًا } رَوَاهُ اَلْبُخَارِيُّ, وَأَبُو دَاوُدَ وَاللَّفْظُ لَه ُ [1] .
Narrated Umm `Atiyah (RAA): After we were pure, we did not consider the yellow or muddy discharge to be anything (i.e. of the menses blood) [Reported by Al-Bukhari and Abu Dawud and the wording is of Abu Dawud].
