Umm Hani, daughter of Abu Talib (May Allah be pleased with her) reported:
I went to the Messenger of Allah (ﷺ) on the day of the conquest of Makkah. He was taking a bath at that time. When he finished the bath, he performed eight Rak'ah (of optional) prayers. This was during the Duha (forenoon).[Al-Bukhari and Muslim]. (JA)
