When a woman having bleeding in between her periods notices signs of cleanliness from her menses

Sahih al-Bukhari · Book 6 · Hadith 331

حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، عَنْ زُهَيْرٍ، قَالَ حَدَّثَنَا هِشَامٌ، عَنْ عُرْوَةَ، عَنْ عَائِشَةَ، قَالَتْ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ إِذَا أَقْبَلَتِ الْحَيْضَةُ فَدَعِي الصَّلاَةَ، وَإِذَا أَدْبَرَتْ فَاغْسِلِي عَنْكِ الدَّمَ وَصَلِّي ‏"‏‏.‏

Narrated `Aisha: The Prophet (ﷺ) said to me, "Give up the prayer when your menses begin and when it has finished, wash the blood off your body (take a bath) and start praying."
