question #3 Sahih al-Bukhari 1179, Book 19, Hadith 57 : What does this narration suggest about the Prophet’s (ﷺ) acceptance of hospitality from his companions?

I heard Anas bin Malik al-Ansari saying, “An Ansari man, who was very
fat, said to the Prophet, ‘I am unable to present myself for the
prayer with you.’ He prepared a meal for the Prophet (ﷺ) and invited him
to his house. He washed one side of a mat with water and the Prophet (ﷺ)
offered two Rakat on it.” So and so, the son of so and so, the son of
Al-Jarud asked Anas, “Did the Prophet (ﷺ) use to offer the Duha prayer?”
Anas replied, “I never saw him praying (the Duha prayer) except on
that day.”
