2:184. O ye who believe ! fasting is prescribed for you, as it was prescribed for those before you, so that you may guard against evil.

2:185. The prescribed fasting is for a fixed number of days, but whoso among you is sick or on a journey, shall fast the same number of other days; and for those who are able to fast only with great difficulty, is an expiation – the feeding of a poor man. And whoso does good of his own accord it is better for him. And fasting is good for you, if you only knew.

2: 186 The month of Ramadan is that in which the Qur’an was sent down as a guidance for mankind with clear proofs of guidance and discrimination.
