Fasting!! The month of Ramadan is the one in which the Qur'an was sent down - right Guidance to mankind, and clear signs of Guidance and Distinction of truth from falsehood. Those among you who witness it, let him fast therein. Whoever is sick or on a journey, then a number of other days. God desires ease for you, and desires not hardship. Thus may you fulfil the number of days assigned, magify God for having guided you, and perhaps you will be thankful. Ramadan is a time of reflecting , believing and worshiping God. Muslims are expected to put more effort into following the teachings of Islam and to avoid obscene and irreligious sights and sounds. Purity of both thoughts and actions is important. The act of fasting is said to redirect the heart away from worldly activities, its purpose being to cleanse the inner soul and free it from harm. It also teaches Muslims to practice self-discipline, self-control, sacrifice, and empathy for those who are less fortunate; thus encouraging actions of generosity and charity Muslims should start observing the fasting ritual upon reaching the age of 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. While fasting is not considered compulsory in childhood, many children endeavour to complete as many fasts as possible as practice for later life. Lastly, those traveling (musaafir) are exempt, but must make up the days they miss. More specifically, Twelver Shī'ah define those who travel more than 14 mi (23 km) in a day as exempt.
