وَمَا تَرَاهُ الْمَرْأَةُ مِنَ الْحُمْرَةِ وَالصُّفْرَةِ وَالْكُدْرَةِ فِي أَيَّامِ الْحَيْضِ فَهُوَ حَيْضٌ، حَتَّى تَرَى الْبَيَاضَ خَالِصًا.
Meaning: Whatever redness, yellowness or brownish discharge she observes within the menstrual days counts as hayd, until she sees complete whiteness.
Humrah means red, sufrah yellow, and kudrah a brownish or turbid discharge. The text qualifies the ruling with “during menstrual days”; it should not be extended automatically to every coloured discharge at every time.
