أَخْبَرَنَا يَزِيدُ بْنُ هَارُونَ، حَدَّثَنَا يَحْيَى، أَنَّ سُمَيًّا مَوْلَى أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ الْحَارِثِ بْنِ هِشَامٍ أَخْبَرَهُ، أَنَّ الْقَعْقَاعَ بْنَ حَكِيمٍ، وَزَيْدَ بْنَ أَسْلَمَ أَرْسَلَاهُ إِلَى سَعِيدِ بْنِ الْمُسَيِّبِ يَسْأَلُهُ كَيْفَ تَغْتَسِلُ الْمُسْتَحَاضَةُ ؟، فَقَالَ سَعِيدٌ: "تَغْتَسِلُ مِنْ الظُّهْرِ إِلَى مِثْلِهَا مِنْ الْغَدِ لِصَلَاةِ الظُّهْرِ، فَإِنْ غَلَبَهَا الدَّمُ اسْتَثْفَرَتْ، وَتَوَضَّأَتْ لِكُلِّ صَلَاةٍ، وَصَلَّتْ".
Qaqa' bin Hakim and Zaid bin Aslam sent Sumi to Sa'id bin al-Musayyib to ask him about a woman with continuous bleeding (mustahadah): how should she perform ghusl (ritual bath)? Sa'id said: She should perform ghusl once for the period from one Dhuhr (noon prayer) to the next day's Dhuhr. If the blood is excessive, she should tie a cloth around herself and perform wudu (ablution) and then offer the prayer.
