[Machine] I experienced irregular bleeding, so I went to the Prophet ﷺ and he said, "Put on a cloth and tie a knot tightly." I said, "O Messenger of Allah, this is worse than that, as I get heavy bleeding." He said, "Enter the state of ritual impurity, seek forgiveness, and menstruate according to the knowledge of Allah. Every month, for six or seven days, then perform ghusl, fast, and pray three days, or twenty-three or twenty-four. Delay Dhuhr prayer and hasten Asr prayer, and perform ghusl for both of them. And perform ghusl for Fajr prayer. This is the most beloved of the two matters to me."
اسْتُحِضْتُ حَيْضَةً مُنْكَرَةً فَأَتَيْتُ النَّبِيَّ ﷺ فَقَالَ «تَلَجَّمِي واحْتَشِي كُرْسُفًا» قَالَتْ يَا رَسُولَ اللهِ هُوَ أَشَدُّ مِنْ ذَلِكَ إِنِّي أَثُجُّهُ ثَجًّا قَالَ فاسْتَدْخِلِي وَاسْتَثْفِرِي وَتَحَيَّضِي فِي عَلِمِ اللهِ فِي كُلِّ شَهْرٍ سِتَّةَ أَيَّامٍ أَوْ سَبْعَةً فَاغْتَسِلِي وَصُومِي وَصَلِّي ثَلَاثًا وَعِشْرِينَ أَوْ أَرْبَعًا وَعِشْرِينَ وَأَخِّرِي الظُّهْرَ وَقَدِّمِي الْعَصْرَ وَاغْتَسِلِي لَهُمَا غُسْلًا وَاغْتَسِلِي لِلْفَجْرِ وَهَذَا أَحَبُّ الْأَمْرَيْنِ إِلَيَّ
