Fasting

The month of Ramadan is when the Quran was revealed, a guidance for humanity, with clear proofs of guidance and discernment. So, whoever witnesses the month should fast. But if anyone is ill or traveling, let them make up the days later. Allah desires ease for you, not hardship, so that you may complete the prescribed period and glorify Him for guiding you, and so that you may be grateful.

2:185The month of Ramadan in which was revealed the Qur'an, a guidance for mankind, and clear proofs of the guidance, and the Criterion (of right and wrong). And whosoever of you is present, let him fast the month, and whosoever of you is sick or on a journey, (let him fast the same) number of other days. Allah desireth for you ease; He desireth not hardship for you; and (He desireth) that ye should complete the period, and that ye should magnify Allah for having guided you, and that peradventure ye may be thankful.
