It was narrated from Umm Hani’ that she went to the Prophet ﷺ on the day of the Conquest (of Makkah) and found him performing Ghusl while Fatimah was concealing him with a garment. She gave him Salams and he said: “Who is this?” She said: “Umm Hani’.” When he had finished his Ghusl he stood up and prayed eight Rak’ahs wrapped in a garment. (Sahih)
