For a certain number of days; but whoever among you is sick or on a journey, then (he shall fast) a (like) number of other days; and those who are not able to do it may effect a redemption by feeding a poor man; so whoever does good spontaneously it is better for him; and that you fast is better for you if you know.

And let not those deem, who are niggardly in giving away that which Allah has granted them out of His grace, that it is good for them; nay, it is worse for them; they shall have that whereof they were niggardly made to cleave to their necks on the resurrection day; and Allah's is the heritage of the heavens and the earth; and Allah is aware of what you do.
