FASTING

Believers, fasting has been prescribed for you, just as it was prescribed for those before you, so that you may guard yourselves against evil. Fast for a specified number of days, but if any one among you is ill or on a journey, let him fast the same number of days later. For those who can fast only with extreme difficulty, there is a way to compensate—the feeding of a needy person. But he who does good of his own accord shall be well rewarded; but to fast is better for you, if you only knew. The month of Ramadan is the month when the Quran was sent down as guidance for mankind with clear proofs of guidance and the criterion by which to distinguish right from wrong. Therefore, whoever of you is present in that month, let him fast; but he who is ill or on a journey shall fast a similar number of days later on. God desires ease for you, not hardship. He desires you to fast the whole month, so that you may glorify Him for His having guided you and so that you may be grateful to Him.
