(a) It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: I would tie on a waist-wrap while I was menstruating, and I would get under one quilt with the Messenger of Allah (peace and blessings be upon him). (b) The hadiths that have passed in the chapter before this are more authentic and clearer, and it is possible that what is meant by whatever may be authentic of these hadiths is what is made clear in those hadiths. And Allah knows best.
