سنن ابن ماجه

It was narrated that ‘Abdullah bin Harith said: “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.”
