Though there is the same amount of Nisab for Sadaqah-e-Fiṭr as for Zakah (as stated above), there is no such condition for Sadaqah-e-Fiṭr as increase in wealth and the passing of a whole year. Likewise, if there are such things that are surplus to requirements (for example, such domestic things that are not used daily) and, if their value reaches the level of Nisab, Sadaqah-e-Fiṭr will be Wajib on account of these things. (Waqar-ul-Fatawa, pp. 385, vol. 2) This difference between the Nisab of Zakah and that of Sadaqah-e-Fitr depends upon the condition of a person.

1.         In addition to paying his own Sadaqah-e-Fiṭr, it is also Wajib for a Sahib-e-Nisab man to pay Sadaqah-e-Fiṭr on behalf of his young children (who are minors). If he has any insane child, he has to pay on behalf of that child as well, even if the insane child has reached puberty. However, if the insane child or young children are Sahib-e-Nisab, the Sadaqah may be paid from their own wealth. (Fatawa ‘Alamgiri, pp. 192, vol. 1)

2.         It is not Wajib for a Sahib-e-Nisab man to pay the Fiṭrah for his wife, parents, younger brothers and sisters and other relatives. (Fatawa ‘Alamgiri, pp. 193, vol. 1)

3.         In case of father’s demise, it is Wajib for the grandfather to pay the Sadaqah-e-Fiṭr for his poor and orphan grandsons and granddaughters. (Durr-e-Mukhtar, Rad-dul-Muhtar, pp. 315, vol. 2)

4.         It is not Wajib for a mother to pay Sadaqah-e-Fiṭr on behalf of her young children. (Rad-dul-Muhtar, pp. 315, vol. 3)

5.         It is not Wajib for a father to pay the Sadaqah-e-Fiṭr for his sane and adult offspring. (Durr-e-Mukhtar, Rad-dul-Muhtar, pp. 317, vol. 3)

6.         If somebody did not fast in Ramadan either due to any valid exemption or, Allah عَزَّوَجَلَّ forbid, without a valid reason, Sadaqah-e-Fiṭr will still be Wajib for him provided he is a Sahib-e-Nisab. (Rad-dul-Muhtar, pp. 315, vol. 3)

Sadaqah-e-Fiṭr will be valid if a man pays it on behalf of his wife or adult offspring (whose necessities like food, clothing etc. he is responsible for) even without their permission. However, if he is not responsible for their necessities, for example, he has a married son who lives in his own home
