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].

وعن أم هانئ فاختة بنت أبي طالب رضي الله عنها قالت: ذهبت إلى رسول الله ﷺ عام الفتح فوجدته يغتسل فلما فرغ من غسله صلى ثمان ركعات، وذلك ضحى" ((متفق عليه وهذا مختصر لفظ إحدى روايات مسلم))
