The amount to be paid as Zakat-ul-Fitr

Q: What is the amount of Zakat-ul-fitr (obligatory charity paid before the Festival of Breaking the Fast) in kilogram? I have given out an amount of ten kilograms of rice on behalf of four members of my family, but later I doubted and asked about the amount due on every single individual and was told that it is 2.25 kg.I hope Your Eminence would inform me of the amount in kilograms, and what should I do if the amount I gave out fell short of the due amount? Please give us Fatwa. May Allah reward you with the best. (Part No. 8; Page No. 266

A: The amount of Zakat-ul-Fitr which is due on every individual is about three kilograms of rice or other staple foodstuffs of the region where one lives. Accordingly, the questioner should make up for the incomplete amounts remaining as due Zakat-ul-Fitr on behalf of those four persons.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
