“The month of Ramadan, in which the Qur'an was sent down as guidance for people, and as clear signs of Guidance and the Criterion (between truth and falsehood). Therefore whoever of you is present this month must fast it, and whoever is so ill that he cannot fast or is on a journey (must fast the same) number of other days. God wills ease for you, and He does not will hardship for you...” The Qur'an, Al-Baqarah (The Cow) 2: 185
