Answer:

Allah says: “Fast for a prescribed number of days. But if anyone among you is ill or traveling, they may fast an equal number of days after Ramaḍân. Those who find fasting extremely difficult may compensate by feeding a needy person for each day missed. And whoever gives more voluntarily, it is better for them. Yet fasting is best for you, if only you knew.”

This verse highlights that those unable to fast due to illness, travel, or significant hardship are required to provide expiation by feeding a poor person for every missed day of fasting. The cost of this expiation varies depending on local living standards. For example, in Canada, the cost of a full meal could range from $15 to $20; in India, it may be considerably less. Rates differ from country to country.

Those who are financially able to give more are encouraged to do so, as greater generosity brings greater rewards and blessings.

In conclusion, if someone misses all thirty days of fasting in Ramaḍân, they would need to compensate by paying approximately $450. This amount can be paid either at the beginning of the month or daily.
