Selling PlayStation to non-Muslims
Question

                I live in New York and I run an online business that sells Playstation portables and its accessories. I saw on your site the ruling on selling playstations, and am wondering what is the ruling on selling it to a Kafir, and what is the ruling on selling its accessories such as memory cards, headphones, and protection cases?.
Praise be to Allah.
      Firstly: 

    There is no differentiation between Muslims and non-Muslims 
    when it comes to that which it is haraam to sell and deal in. Everything 
    that it is not permissible to sell to a Muslim, it is not permissible to 
    sell it to a kaafir either. 

    That is because the rulings of sharee‘ah are also addressed 
    to the kuffaar, according to the correct scholarly view; everything that is 
    obligatory for the Muslims to do is also obligatory for the kuffaar, and 
    everything that is forbidden to Muslims is also forbidden to them. 

    Al-Haafiz Wali al-Deen al-‘Iraaqi said: The correct view, 
    which is that of the scholars and the majority is that the rules of 
    sharee‘ah are also addressed to the kuffaar, so silk is forbidden to them as 
    it is forbidden to the Muslims. End quote.

    Tarh al-Tathreeb, 3/227 

    Shaykh al-Islam Ibn Taymiyah said: It is not permissible for 
    a man to help anyone in disobeying Allah, even if the one who is being 
    helped does not believe that it is a sin, such as helping the disbelievers 
    with alcohol and pork. End quote.

    Al-Fataawa al-Kubra, 6/282 

    The Shaafa‘i faqeeh Ibn Hajar al-Haytami was asked about the 
    ruling on selling musk to a kaafir whom he knows is buying it to apply to 
    his idol, or selling an animal to a harbi (a non-Muslim who is in a state of 
    war with Muslims) who he knows is going to kill it without slaughtering it 
    properly in order to eat it. 

    He replied: It is haraam to sell in both cases. In every case 
    where the seller knows that the buyer is going to use (the item) for sinful 
    purposes, it is haraam for him to sell it to him. Applying perfume to idols 
    and killing animals for food without slaughtering them properly are two 
    major sins even for them, because the correct view is that the rules of 
    sharee‘ah are addressed to the kuffaar just as they are addressed to the 
    Muslims. So it is not permissible to help anyone with them by selling 
    anything that may help them to do those things. End quote from al-Fataawa 
    al-Fiqhiyyah al-Kubra, 5/43

    Secondly: 

    The ruling on selling accessories for PlayStation is the same 
    as the ruling on selling PlayStation itself. It is permissible to sell it to 
    a person who you think is most likely to use the PlayStation in permissible 
    ways, and it is haraam to sell it to a person who you think is most likely 
    to use it in haraam ways. 

    If you do not know anything about the purchaser, then you 
    should proceed on the basis of how most people use it in the country where 
    you live. If most people use it in haraam ways, then it is haraam to sell 
    it, and if most people use it in permissible ways, then it is permissible to 
    sell it. It says in Fataawa al-Lajnah al-Daa’imah (13/109): 
    Everything that is used in haraam ways, or it is thought most likely that 
    that is the case, it is haraam to manufacture it, import it, or distribute 
    it among the Muslims. End quote.
