Question:
What if one forgets to pay Zakat al-Fitr before Eid Prayer?
Answer:
Walaikum assalam,
It is not sinful to delay paying one�s zakat al-fitr until after the
Eid prayer, though it is improper (and somewhat disliked) to do so,
because it is recommended to pay it onEid day, before the prayer, when
possible. [Shaykh Zada/Halabi, Majma` al-Anhur Multaqa al-Abhur,1.228;
Ibn Abidin, Radd al-Muhtar]
Shaykh Zada said in Majma` al-Anhur, commenting on Imam Ibrahim
al-Halabi�s Multaqa al-Abhur, which constitute the clearest commentary
and primer, respectively, in the Hanafi school,
�(It is valid to pay it before) the day of Eid� (without any
difference between [a short] period and [a long] period)� even
hastened by ten years or more, as is the sound and chosen position
mentioned in most recognized texts [of the Hanafi school, f: and this
was confirmed as being the fatwa position in Haskafi�s Durr al-Mukhtar
and Ibn Abidin�s Radd al-Muhtar]�
(It is recommended to pay the fitr charity before Eid prayer) after sunrise�
(However, the obligation) of fitr charity (is not lifted by delaying),
and such a delay is not [f: prohibitively] disliked [f: rather, as Ibn
Abidin states, it is somewhat disliked], even if long and will still
be considered a current performance and not a makeup, though there is
impropriety in it�� [Majma` al-Anur, 1.228]
And Allah alone gives success.
