Practices during Ramadan
It becomes compulsory for Muslims to start fasting when they reach puberty, so long as they are healthy, sane and have no disabilities or illnesses. The elderly, the chronically ill, and the mentally ill are exempt from fasting, although the first two groups must endeavor to feed the poor in place of their missed fasting. Also exempt are pregnant women if they believe it would be harmful to them or the unborn baby, women during the period of their menstruation, and women nursing their newborns. A difference of opinion exists among Islamic scholars as to whether this last group must make up the days they miss at a later date, or feed poor people as a recompense for days missed.
