“During the caliphate
of
‘Uthman, when the people were present in large numbers, I asked
about Duha prayer, and I could not find anyone who could tell me that
he, meaning the Prophet (ﷺ), had prayed it, apart from Umm Hani’.
She told me that he had prayed it with eight Rak’ah.”
Sunan Ibn Majah Book 5, Hadith 577
