سنن نسائی · Hadith 2325

It was narrated from ‘Ata’ from Ibn ‘Abbas concerning this Verse — “And as for those who can fast with difficulty, (e.g. an old man), they have (a choice either to fast or) to feed a MiskIn (poor person) (for every day).” — that for those who can fast with difficulty means they find it hard; to feed a MiskIn means ….rng one poor person for each ‘ does good of his accord means feeding another person. This is not abrogated, it is better for him. And: that “you fast is better for you” means there is no concession regarding this except for those who are not able to fast, or who are incurably sick. (Sahih)
