Is it permissible for him to ask the company for accommodation if it will be built with a riba-based loan?
Question

                Is it permissible to ask the company for accommodation if it will be built by an interest based loan? Then the company will valuate these buildings and sell them to its clerks in return for installments that will be discounted from their salaries? The price of the accommodation will mostly be very high; to cover the cost of building, the mortgage, and a profit for the company. Some brothers who we think are religious have already asked to buy accommodation from the company considering it normal buying-selling process.
Praise be to Allah.
    There are two issues to do with riba which must be dealt with 
    separately. 

    1 –  

    Causing riba to take place, such as if one of them asks 
    another to take out a riba-based loan for him, or some of them act as a 
    guarantor for someone who will get a riba-based loan from the bank and so 
    on, which is helping and causing people to fall into this major sin. 

    Undoubtedly this kind is haraam, because the one who causes 
    others to fall into something haraam has a share of the sin, as Allaah says 
    (interpretation of the meaning): “but do not help one another in sin and 
    transgression” [al-Maa’idah 5:1]. 

    There is a particularly strong warning against causing people 
    to fall into riba, in the hadeeth of Jaabir ibn ‘Abd-Allaah (may Allaah be 
    pleased with him) who said: The Messenger of Allaah  (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). 

    Al-Nawawi (may Allaah have mercy on him) said: 

    This indicates that it is haraam to help others in 
    falsehood. 

    Sharh Muslim (11/26). 

    When the Prophet  (peace and blessings of Allaah be upon 
    him) cursed khamr (alcohol), he also cursed those who help in its drinking, 
    so he  (peace and blessings of Allaah be upon him) said: “Allaah has 
    cursed khamr and the one who drinks it, the one who pours it, the one who 
    sells it, the one who buys it, the one who squeezes it, the one for whom it 
    is squeezed, the one who carries it and the one to whom it is carried.” 
    Narrated by Abu Dawood (3674) and classed as saheeh by al-Albaani in 
    Saheeh Abi Dawood. The one for whom it is squeezed is the one who asks 
    for it to be squeezed for himself or for someone else. 

    See; Tuhfat al-Ahwadhi (4/430). 

    The same ruling applies to everyone who asks for riba for 
    himself or for someone else and causes it to occur. 

    On our site we have previously posted answers which give 
    scenarios of the prohibition on helping in riba. See for example the answer 
    to question no. 33709. 

    2 –  

    Riba is a kind of earning which is haraam because of the way 
    in which it is acquired, not in and of itself. In the case of that which is 
    haraam because of the way in which it is acquired, the sin is only on the 
    one who acquires it, and there is no sin on the one who deals with the one 
    who acquires it by buying, selling, giving, or receiving hospitality. The 
    evidence for that is that the Prophet  (peace and blessings of Allaah be 
    upon him) would deal with the Jews in Madeenah, buying and selling, and he 
    used to eat with them, although they are the ones whom Allaah described as 
    consuming riba and taking people’s wealth unlawfully. 

    That has been explained in detail in the answers to several 
    questions on our site. Please see no.

    Based on that, there is nothing wrong with buying a house 
    from the company, even if it was built with a riba-based loan, because the 
    sin of that is on the one who agreed with the bank to take out the 
    riba-based loan, or who helped with that, or approved of it. As for the 
    employee who is going to buy the house from the company, there is no sin on 
    him. This is like the Prophet’s dealings with the Jews, who used to consume 
    riba, as stated above. 

    And Allaah knows best.
