Delegating someone to buy something using a credit card
Question

                I am in Africa and needs a good from the US both cannot buy it as it can only be bought using a credit card from a website. However I have a friend in the US who have a credit card and is willing to buy it on the basis that I send him the exact amount he spent. Would this be acceptable in Islam?.
Praise be to Allah.
    It is not permissible to use credit cards which oblige the 
    cardholder to pay a penalty in the event of late payment. This has been 
    discussed in the answer to question number
    97530 and
    11179. 

    If your friend's credit card is free of this condition, then 
    there is nothing wrong with you delegating him to buy what you want and 
    sending him the money later on. 

    But if the card has this condition, then it is not 
    permissible for you to delegate him to buy something for you with this card, 
    because if it is not permissible for a person to do a thing, it is not 
    permissible for him to delegate someone else to do it. 

    It says in al-Mawsoo’ah al-Fiqhiyyah al-Kuwaitiyyah 
    (25/66): It is not acceptable to delegate to someone else that which it is 
    not acceptable for him to do himself, because the agent is acting on his 
    behalf. 

    Shaykh Ibn ‘Uthaymeen said: This is a principle; everyone who 
    has the power to dispose of a thing is entitled to delegate it to someone 
    else or be delegated by someone else; and if he does not have the power to 
    dispose of it, he does not have the right to delegate it to someone else or 
    be delegated by someone else. Al-Sharh al-Mumti’ (9/90). 

    What you have to do is look for another way to buy the items 
    you need, especially as there are now a number of credit cards on which you 
    may put a certain amount of money and then use them within the limits of 
    this amount, without there being any interest or riba. 

    If this credit card is free of this riba-based condition, 
    there is nothing wrong with you delegating your friend to buy things for 
    you, then you can send the money to him later on. This is not regarded as 
    buying currency for currency, in which a hand-to-hand transfer would be 
    stipulated; rather it is a loan to you from your friend. 

    And Allaah knows best.
