Narrated 'Ata:

That he heard Ibn `Abbas reciting the Divine Verse:-- "And for those who can fast they had a choice either fast, or feed a poor for every day.." (2.184) Ibn `Abbas said, "This Verse is not abrogated, but it is meant for old men and old women who have no strength to fast, so they should feed one poor person for each day of fasting (instead of fasting).

Narrated Nafi`:

Ibn `Umar recited: "They had a choice, either fast or feed a poor for every day.." and added, "This Verse is abrogated."

Narrated Salama:

When the Divine Revelation: "For those who can fast, they had a choice either fast, or feed a poor for every day," (2.184) was revealed, it was permissible for one to give a ransom and give up fasting, till the Verse succeeding it was revealed and abrogated it.

Salama b. Akwa' (Allah be pleased with him) reported that when this verse was revealed: "And as for those who can fast (but do not) expiation is the feeding of a needy person" (ii. 183), (he who liked to observe fast did observe it) and he who felt reluctant to observe it ate and expiated till the verse was revealed which abrogated it.
