[Machine] "About a woman who experiences irregular bleeding during her menstrual period, when her period ends, she should perform a complete ablution (wudu) when it is time for Asr prayer. Then she should take a cloth and seek forgiveness with it. After that, she should pray both Dhuhr and Asr prayers together. Then she should do the same and pray Maghrib and Isha prayers together. Finally, she should do the same and pray Fajr prayer."  

الدارمي:٨٣٢أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى عَنْ عُثْمَانَ بْنِ الْأَسْوَدِ

عَنْ مُجَاهِدٍ فِي الْمُسْتَحَاضَةِ «إِذَا خَلَفَتْ قُرُوءَهَا فَإِذَا كَانَ عِنْدَ الْعَصْرِ تَوَضَّأَتْ وُضُوءًا سَابِغًا ثُمَّ لِتَأْخُذْ ثَوْبًا فَلْتَسْتَثْفِرْ بِهِ ثُمَّ لِتُصَلِّ الظُّهْرَ وَالْعَصْرَ جَمِيعًا ثُمَّ لِتَفْعَلْ مِثْلَ ذَلِكَ ثُمَّ لِتُصَلِّ الْمَغْرِبَ وَالْعِشَاءَ جَمِيعًا ثُمَّ لِتَفْعَلْ مِثْلَ ذَلِكَ ثُمَّ لِتُصَلِّ الصُّبْحَ»
