בבא קמא פרק ו משנה ה

(5) One who set fire to a stack of sheaves and in it there were utensils and these caught fire: Rabbi Yehudah says: He must pay back for what was in it. But the Sages say: He pays only for a stack of wheat or barley. If a kid was fastened to it and a slave stood near by, and they were burnt together, he is liable. If there was a slave fastened to it and a kid stood near by and they were burnt together, he is not liable. And the Sages agree with Rabbi Yehudah that if one set fire to a large building, he must pay back for everything in it; for such is the customary for people to leave [their items] in their houses.
