Women who are in the family way, maids, those in confinement due to delivery, and those who are ailing, should take their food at night (not keeping the full fast). If one is in her menses, and so cannot observe it through impurity, she should get it observed by others, according to the prescribed rites. She herself should observe continence.—35.
