Should he take a riba-based loan if he does not intend to pay the interest?
Question

                My question is: Someone lives in a foreign country wants to take a mortgage from a bank there. Then  he will return to his country and use the money for business. Then pay the mortgage back without interest. If he takes for example $10000 by $5000 interest, he will pay it back only as $10000 to avoid the interest. Will this be considered stealing if they agree that he must pay the interest? Even if the bank is not Islamic?.
Praise be to Allah.
    Firstly: 

    A loan agreement that includes riba is a haraam contract 
    according to sharee’ah, and it is not permissible to enter into it, even if 
    the borrower intends not to pay the interest. The Prophet  (peace and 
    blessings of Allaah be upon him) cursed the one who consumes riba and the 
    one who pays it, the one who writes it down and the two who witness it, and 
    he said: they are all the same. Narrated by Muslim (1598). 

    Signing an agreement to pay riba and entering into the 
    contract implies that one is committing to paying the riba that Allaah and 
    His Messenger have forbidden, so he is included in this stern warning. 

    Secondly: 

    Riba is haraam and is a major sin whether the transaction is 
    between Muslims or between a Muslim and a kaafir, because of the general 
    meaning of the evidence from the Qur’aan and Sunnah which forbids riba. 
    There is no exception for transactions between a Muslim and a kaafir. See 
    the answer to question no. 8141. 

    And Allaah knows best.
