Al-Adab al-Mufrad

It is narrated from Muhammad bin Ziyad, may Allah have mercy on him, that he said: I found the Salaf (the Companions and the Followers) living with their families in the same house. Whenever any of them had a guest and their pot was cooking, the one with the guest would take it for his guest. When the owner of the pot found the pot missing, he would ask, "Who has taken the pot?" The one with the guest would say, "We have taken it for the guest." The owner of the pot would say, "May Allah bless you in it," or would say words to that effect. Baqiyyah, may Allah have mercy on him, said that Muhammad said: And when they baked bread, it would be the same, and there was only a bamboo wall between their houses. Baqiyyah, may Allah have mercy on him, said: And I also found my teacher Muhammad and his companions upon this way.
