[Fasting for] a limited number of days. So whoever among you is (2:184)

﴿أَيَّامًا مَّعْدُودَاتٍ ۚ فَمَن كَانَ مِنكُم مَّرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ ۚ وَعَلَى الَّذِينَ يُطِيقُونَهُ فِدْيَةٌ طَعَامُ مِسْكِينٍ ۖ فَمَن تَطَوَّعَ خَيْرًا فَهُوَ خَيْرٌ لَّهُ ۚ وَأَن تَصُومُوا خَيْرٌ لَّكُمْ ۖ إِن كُنتُمْ تَعْلَمُونَ﴾
[ البقرة: 184]

2:184 [Fasting for] a limited number of days. So whoever among you is ill or on a journey [during them] - then an equal number of 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 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.

[Observing Saum (fasts)] for a fixed number of days, but if any of you is ill or on a journey, the same number (should be made up) from other days. And as for those who can fast with difficulty, (e.g. an old man, etc.), they have (a choice either to fast or) to feed a Miskin (poor person) (for every day). But whoever does good of his own accord, it is better for him. And that you fast, it is better for you if only you know.

(Fasting) for a fixed number of days; but if any of you is ill, or on a journey, the prescribed number (Should be made up) from days later. For those who can do it (With hardship), is a ransom, the feeding of one that is indigent. But he that will give more, of his own free will,- it is better for him. And it is better for you that ye fast, if ye only knew.
