Is the zakaat al-fitr that his father paid on his behalf in cash acceptable?
Question

                My father pays zakaat al-fitr on behalf of me and my siblings every year in cash, based on the fatwas of some of the scholars. I have tried repeatedly on many occasions to convince him that this view is not the most correct one, because according to the the majority of scholars, zakaat al-fitr must be paid in the form of the things mentioned in the hadeeths, but he is not convinced. Should I pay zakaat al-fitr on behalf of myself as it is stated in the hadeeth? 

Please note that I am still a student at University and my wealth is what I have saved from the money that my father gives me for my needs.
Praise be to Allah.
    Paying zakaat al-fitr in cash is not acceptable according to 
    the majority of scholars, because the Prophet (blessings and peace of Allah 
    be upon him) enjoined that it be given in the form of the local staple food, 
    and it is not known that he or any of his Companions gave it in the form of 
    money. 

    Al-Nawawi said in al-Majmoo’ (6/113): 

    It is not acceptable to pay the cash value of zakaat al-fitr 
    in our view. This was also the view of Maalik, Ahmad and Ibn al-Mundhir. 

    Abu Haneefah said: It is permissible. This was narrated by 
    Ibn al-Mundhir from al-Hasan al-Basri, ‘Umar ibn ‘Abd al-‘Azeez and 
    al-Thawri. 

    He said: And Ishaaq and Abu Thawr said that it is not 
    acceptable except in case of necessity. End quote. 

    See: al-Mawsoo'ah al-Fiqhiyyah, 23/343-344. 

    See also the answer to question no.
    22888. 

    If a person follows the view of the Hanafis, ‘Umar ibn ‘Abd 
    al-‘Azeez and al-Hasan al-Basri, that it is permissible to give the value of 
    zakaat al-fitr in cash, based on the evidence that he regards as more 
    correct, or following the scholars who said that, it is acceptable in sha 
    Allah. 

    Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) was 
    asked: 

    If a person pays zakaat al-fitr in cash, following the 
    opinion of the scholars of his country, then comes to learn the more correct 
    view, what should he do with regard to his charity??  

    He replied: 

    He does not have to do anything. If a person does something 
    on the basis of a fatwa from a scholar or following the scholars of his 
    country, he does not have to do anything. An example of that is if a woman 
    does not pay zakaah on her jewellery and remains for several years not 
    knowing that zakaah is due on jewellery, or on the basis that her scholars 
    have advised her that no zakaah is due on it, then she learns the ruling; 
    she has to pay zakaah after she learns the ruling, but before that she does 
    not have to. End quote. 

    Liqaa’aat al-Baab al-Maftooh, 
    no. 191, question no. 19 

    Thus it is clear that if your father pays zakaat al-fitr on 
    your behalf in cash -- based on his following the scholars whose opinion 
    that is -- it is acceptable and valid, and you do not have to do it again in 
    the form of food so long as your father is responsible for spending on you 
    and you are not yet spending on yourself independently. 

    And Allah knows best.
