Hadith 48130

Muhammad bin Ziyad said that he found that the predecessors (that is, the companions and their successors) lived together with their families. When a guest of one of them arrived and he found the cooking pot of another on the stove, he would take it serve his guest from it. When the owner of the cooking pot found it missing, he would enquire and the man who had taken it would tell him that he took it for his guest. There upon the owner would exclaim." May Allah bless it for you," or he would make a similar exclamation. And Muhammad said, when bread was baked (the one with the guest would take all of it). Their homes were separated by walls made of canes". A narration of the Hadith, Baqiyyah, said," I too found (my teacher) Muhammad bin Ziyad and his colleagues observe this practice.
