 Reading Maimonides taught that if a person sees a lost object and the person's father says not to return it, the person should return it instead of obeying the person's father.For by obeying the father and fulfilling the positive commandment “Honor your father” in  the person would violate the positive commandment “And you shall certainly return it,” as well as the negative commandment “You may not ignore it.” And reading “"All" objects lost by your colleague,” Maimonides taught that if a person sees flood waters coming that will ruin a building or a field belonging to a colleague, the person is obligated to put up a barrier before the waters to check them.Maimonides said that the mention of “All” in includes the devastation of property.
