So who says that his guardian fasts on his behalf, and who says that no one fasts on behalf of anyone else? The people of this opinion differed. Some of them said that his guardian should feed on his behalf, and some of them said that there is no fasting or feeding unless it is recommended. Some said that he fasts, and if he is not able to feed, some people differentiate between a vow and fasting. They said that his guardian should fast on his behalf during the vow, but he should not fast during the obligatory fast .
