The World Federation One Stop Fiqh

Ruling 1668

If a person has to keep qaḍāʾ fasts for a number of Ramadans and he does not specify in his intention which month of Ramadan he is keeping a qaḍāʾ fast for, it will not be regarded as the qaḍāʾ fast for the last year; as a result, the kaffārah for delaying its qaḍāʾ would not be waived.11
