Question: I heard on the program ‘Nūr ‘alā ad-Darb’ in reply to a question that it is obligatory that the feeding (expiation for not fasting) is NOT to restricted to one poor person, but rather for every day missed, a different poor person is to be fed.
Answer: Concerning this matter I am not aware of it being obligatory to feed a multiple of poor persons when making the expiation for missed fasts. Allāh, the Majestic, the Most-High, says:
“As for those who can fast with difficulty, they have (a choice either to fast or)
to feed a Miskīn (needy person) (for every day).”
And so long as the person concerned carries out the expiation of feeding and was to do so with one poor person, I hope and see that as being sufficient, if Allāh wills.
