Narrated Anas bin Seereen: I heard Anas saying, A man from Ansar said to the Prophet, 'I cannot pray with you (in congregation).' He was a very fat man and he prepared a meal for the Prophet and invited him to his house. He spread out a mat for the Prophet, and washed one of its sides with water, and the Prophet prayed two rak`at on it. A man from the family of Al-Jaruid [??] asked, Did the Prophet used to pray the Duha (forenoon) prayer? Anas said, I did not see him praying the Duha prayer except on that day.
