1. Purification
١۔ كتاب الطهارة
"I entered upon 'Aishah and asked her: 'Did the Messenger of Allah ﷺ perform Ghusl at the beginning of the night or at the end?' She said: 'Both. Sometimes he performed Ghusl at the beginning and sometimes at the end.' I said: 'Praise be to Allah who has made the matter flexible.'"
