Hamnah said my menstruation was great in quantity and severe. So I came to the Messenger of Allah ﷺ for a decision and told him. I found him in the house of my sister, Zaynab, daughter of Jahsh. I said: Messenger of Allah, I am a woman who menstruates in great quantity and it is severe, so what do you think about it? It has prevented me from praying and fasting. He said: I suggest that you should use cotton, for it absorbs the blood. She replied: It is too copious for that. He said: Then take a cloth. She replied: It is too copious for that, for my blood keeps flowing. The Messenger of Allah ﷺ said: I shall give you two commands; whichever of them you follow, that will be sufficient for you without the other, but you know best whether you are strong enough to follow both of them. He added: This is a stroke of the Devil, so observe your menses for six or seven days, Allah alone knows which it should be; then wash. And when you see that you are purified and quite clean, pray during twenty-three or twenty-four days and nights and fast, for that will be enough for you, and do so every month, just as women menstruate and are purified at the time of their menstruation and their purification. But if you are strong enough to delay the noon (Zuhr) prayer and advance the afternoon ('Asr) prayer, to wash, and then combine the noon and the afternoon prayer; to delay the sunset prayer and advance the night prayer, to wash, and then combine the two prayers, do so: and to wash at dawn, do so: and fast if you are able to do so if possible. The Messenger of Allah ﷺ said: Of the two commands this is more to my liking.1 Abu Dawud said: 'Amr b. Thabit narrated from Ibn 'Aqil: Hamnah said: Of the two commands this is the one which is more to my liking.2 In this version these words were not quoted as the statement of the Prophet ﷺ; it gives it as a statement of Hamnah. Abu Dawud said: 'Amr b. Thabit was a Rafidi. This has been said by Yahya b. Ma'in. Abu Dawud said: I heard Ahmad (b. Hanbal) say: I am doubtful about the tradition transmitted by Ibn 'Aqil.

كُنْتُ أُسْتَحَاضُ حَيْضَةً شَدِيدَةً كَثِيرَةً فَجِئْتُ رَسُولَ اللهِ ﷺ أَسْتَفْتِيهِ وَأُخْبِرُهُ فَوَجَدْتُهُ فِي بَيْتِ أُخْتِي زَيْنَبَ بِنْتِ جَحْشٍ قَالَتْ فَقُلْتُ يَا رَسُولَ اللهِ إِنَّ لِي إِلَيْكَ حَاجَةً فَقَالَ وَمَا هِيَ فَقُلْتُ يَا رَسُولَ اللهِ إِنِّي أُسْتَحَاضُ حَيْضَةً كَثِيرَةً شَدِيدَةً فَمَا تَرَى فِيهَا قَدْ مَنَعَتْنِي الصَّلَاةَ وَالصِّيَامَ قَالَ أَنْعَتُ لَكِ الْكُرْسُفَ فَإِنَّهُ يُذْهِبُ الدَّمَ قَالَتْ هُوَ أَكْثَرُ مِنْ ذَلِكَ قَالَ فَتَلَجَّمِي قَالَتْ إِنَّمَا أَثُجُّ ثَجًّا فَقَالَ لَهَا سَآمُرُكِ بِأَمْرَيْنِ أَيَّهُمَا فَعَلْتِ فَقَدْ أَجْزَأَ عَنْكِ مِنَ الْآخَرِ فَإِنْ قَوِيتِ عَلَيْهِمَا فَأَنْتِ أَعْلَمُ فَقَالَ لَهَا إِنَّمَا هَذِهِ رَكْضَةٌ مِنْ رَكَضَاتِ الشَّيْطَانِ فَتَحَيَّضِي سِتَّةَ أَيَّامٍ أَوْ سَبْعَةً فِي عِلْمِ اللهِ ثُمَّ اغْتَسِلِي حَتَّى إِذَا رَأَيْتِ أَنَّكِ قَدْ طَهُرْتِوَاسْتَنْقَأْتِ فَصَلِّي أَرْبَعًا وَعِشْرِينَ لَيْلَةً أَوْ ثَلَاثًا وَعِشْرِينَ لَيْلَةً وَأَيَّامَهَا وَصُومِي فَإِنَّ ذَلِكَ يُجْزِئُكِ وَكَذَلِكَ فَافْعَلِي فِي كُلِّ شَهْرٍ كَمَا تَحِيضُ النِّسَاءُ وَكَمَا يَطْهُرْنَ بِمِيقَاتِ حَيْضِهِنَّ وَطُهْرِهِنَّ وَإِنْ قَوِيتِ عَلَى أَنْ تُؤَخِّرِي الظُّهْرَ وَتُعَجِّلِي الْعَصْرَ فَتَغْتَسِلِينَ ثُمَّ تُصَلِّينَ الظُّهْرَ وَالْعَصْرَ جَمِيعًا ثُمَّ تُؤَخِّرِينَ الْمَغْرِبَ وَتُعَجِّلِينَ الْعِشَاءَ ثُمَّ تَغْتَسِلِينَ وَتَجْمَعِينَ بَيْنَ الصَّلَاتَيْنِ فَافْعَلِي وَتَغْتَسِلِينَ مَعَ الْفَجْرِ وَتُصَلِّينَ وَكَذَلِكَ فَافْعَلِي وَصَلِّي وَصُومِي إِنْ قَدَرْتِ عَلَى ذَلِكَ وَقَالَ رَسُولُ اللهِ ﷺ وَهَذَا أَعْجَبُ الْأَمْرَيْنِ إِلَيَّ  

She experienced prolonged non-menstrual bleeding during the time of the Messenger of Allah. She came to the Messenger of Allah and said: "I am suffering prolonged and painful bleeding." He said: "Fill it with a pad of cloth." She said: "It is worse than that, it is flowing copiously." He said: "Then bind yourself with a cloth and observe your menses for six or seven days, in the knowledge of Allah, then have a bath and perform prayer and fast for twenty-three or twenty-four days. Delay Zuhr and bring 'Asr forward, and take (one) bath for both, and delay Maghrib and bring 'Isha' forward, and have (one) bath for both. That is what I prefer of the two matters.'" (Using translation from Ibn Mājah 627)  

أَنَّهَا اسْتُحِيضَتْ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ فَأَتَتْ رَسُولَ اللهِ ﷺ فَقَالَتْ يَا رَسُولَ اللهِ إِنِّي اسْتَحَضْتُ حَيْضَةً مُنْكَرَةً شَدِيدَةً فَقَالَ لَهَا احْتَشِي كُرْسُفًا قَالَتْ إِنِّهُ أَشَدُّ مِنْ ذَلِكَ إِنِّي أَثُجُّ ثَجًّا قَالَ تَلَجَّمِي وَتَحَيَّضِي فِي كُلِّ شَهْرٍ فِي عِلْمِ اللهِ سِتَّةَ أَيَّامٍ أَوْ سَبْعَةً ثُمَّ اغْتَسِلِي غُسْلًا وَصَلِّي وَصُومِي ثَلَاثًا وَعِشْرِينَ أَوْ أَرْبَعًا وَعِشْرِينَ وَأَخِّرِي الظُّهْرَ وَقَدِّمِي الْعَصْرَ وَاغْتَسِلِي لَهُمَا غُسْلًا وَأَخِّرِي الْمَغْرِبَ وَقَدِّمِي الْعِشَاءَ وَاغْتَسِلِي لَهُمَا غُسْلًا وَهَذَا أَحَبُّ الْأَمْرَيْنِ إِلَيَّ
