If one is sick, nursing or travelling, one is considered exempt from fasting. Any fasts broken or missed due to sickness, nursing or travelling must be made up whenever the person is able before the next month of Ramadan. According to the Quran, for all other cases, not fasting is only permitted when the act is potentially dangerous to one's health – for example, those who are sick, elderly, or on a journey, and women who are menstruating, pregnant, or nursing are permitted to break the fast, but this must be made up by paying a fidyah which is essentially the iftaar and suhur for a fasting person who requires such financial help.
