[Machine] Um Habibah experienced Istihadah for seven years while she was under the care of Abdul Rahman ibn Auf. The Prophet ﷺ instructed her, saying, "When the menstrual bleeding starts, leave the prayer. And when it stops, perform ablution and pray." This narration is authentic according to the conditions of both Al-Bukhari and Muslim. It was not included by them, but it was included by Muslim in a different narration from Sufyan ibn `Uyaynah and Ibrahim ibn Sa`d, narrated from Az-Zuhri. Muhammad ibn `Amr ibn Alqamah Al-Awza`i also narrated this hadith from Az-Zuhri using the same wording, and it is considered authentic according to the conditions of Muslim, although he did not include it.  

اسْتَحَاضَتْ أُمُّ حَبِيبَةَ وَهِيَ تَحْتَ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ سَبْعَ سِنِينَ فَأَمَرَهَا النَّبِيُّ ﷺ قَالَ «إِذَا أَقْبَلَتِ الْحَيْضَةُ فَدَعِي الصَّلَاةَ فَإِذَا أَدْبَرَتْ فَاغْتَسِلِي وَصَلِّي» «حَدِيثُ عَمْرِو بْنِ الْحَارِثِ وَالْأَوْزَاعِيِّ صَحِيحٌ عَلَى شَرْطِ الشَّيْخَيْنِ وَلَمْ يُخَرِّجَاهُ إِنَّمَا خَرَّجَ مُسْلِمٌ حَدِيثَ سُفْيَانَ بْنِ عُيَيْنَةَ وَإِبْرَاهِيمَ بْنِ سَعْدٍ عَنِ الزُّهْرِيِّ» وَقَدْ تَابَعَ مُحَمَّدَ بْنَ عَمْرِو بْنِ عَلْقَمَةَ الْأَوْزَاعِيَّ عَلَى رِوَايَتِهِ هَذِهِ عَنِ الزُّهْرِيِّ عَلَى هَذِهِ الْأَلْفَاظِ «وَهُوَ صَحِيحٌ عَلَى شَرْطِ مُسْلِمٍ وَلَمْ يُخَرِّجَاهُ» على شرطهما
