(12) باب صَلاَةِ الضُّحَى
Narrated Ibn Abi Laila:
No one told us that the Prophet (ﷺ) had offered Duha prayer except Umm Hani. She said that the Prophet (ﷺ) had taken bath in her house on the day of the Conquest of Mecca and prayed eight rak'ahs. But no one saw him afterwards praying these rak'ahs.
