Why should boys not work at home, and what is the legal evidence that household chores are limited to girls?

It is necessary to observe proper etiquette and a good style when rectifying fatwas. The upbringing of children should be suited to their future: a girl is raised for domestic service, and a boy for work outside the home. Justice must be maintained between children in all matters, even in kisses. Assigning tasks to each of them in organizing household affairs is good and beneficial for training them in order and acquiring good qualities.
