The 'Ulama give various meanings for dafaf. This has been explained in detail in the commentary of hadith number two of this chapter. Although the subject of this hadith is not the same as in the hadith mentioned there. Apparently it means, that when Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam was alone, he partook whatever was available for meals, even if it was only bread or meat. He certainly would make an effort to have both things available when visitors arrived.
