[Fasting for] a limited number of days. So whoever among you is ill or on a journey [during them] - then an equal number of other days [are to be made up]. And upon those who are able [to fast, but with hardship] - a ransom [as substitute] of feeding a poor person [each day]. And whoever volunteers good [i.e., excess] - it is better for him. But to fast is best for you, if you only knew.
You are ordered to fast for a small number of days in the year. Yet whoever of you is ill, with an illness that makes fasting difficult, or travelling, then they do not need to fast; but they can make up for these days by fasting the same number of other days. Those who are able to fast, but do not, should compensate by feeding a poor person for every day they did not fast. Fasting is better for you than not fasting and feeding a poor person instead, if you only knew what goodness there is in fasting. This was the first of Allah’s laws about fasting: whoever wanted to fast did so; and whoever did not want to fast was permitted not to, and fed a poor person instead. Afterwards Allah made fasting a duty for every able person who has reached puberty.
