It was narrated that Ghudaif bin Al-Harith said: “I entered upon Aishah (RA) 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.” (Hasan)
