QURAN About Ramadan Surah Baqrah : 184

    "Whoever of you is present in the month, he shall fast therein, and whoever is sick or upon a journey, then (he shall fast) a (like) number of other days; ALLAH desires ease for you, and He does not desire for you difficulty, and (He desires) that you should complete the number and that you should exalt the greatness of ALLAH for His having guided you and that you may give thanks."
