Can the renter rent out the house that he is renting?
Question

                I live in the USA. A friend has advised me to furnish and rent out a room of the house I am renting, so that it helps me pay the rent and make an extra profit for myself. Is this islamically permissible?.
Praise be to Allah.
    Firstly: 

    It is permissible for the one who is renting a house or 
    anything else to rent it out or rent out part of it to someone else, for the 
    same rent that he is paying or for more or less, because by renting the 
    house he has become the owner of its usufruct, and he may dispose of that 
    usufruct by giving it, renting it out or in other ways, so long as the 
    second renter is going to use it in the same manner as him or less; if he 
    has rented it to live in it, he does not have the right to rent it out to 
    someone who will use it as a workshop and the like. 

    This is the view of the majority of fuqaha’. 

    Ibn Qudaamah (may Allaah have mercy on him) said: It is 
    permissible for the renter to rent out the rented property if he has taken 
    control of it. This was stated by Ahmad and it is the view of al-Shaafa’i 
    and ashaab al-ra’y. 

    It is not permissible to rent it out except to someone who 
    will use it in a similar way, or in a manner that will cause less wear and 
    tear.  

    And it is permissible for the renter to rent out the 
    property, for a similar rent or for more. This was stated by Ahmad and it is 
    the view of al-Shaafa’i. End quote. Al-Mughni (8/54-56). 

    The scholars of the Standing Committee for Issuing Fatwas 
    said: If a person rents a house, apartment or showroom, for example, for a 
    period of time, and he has some time left, it is permissible for him to rent 
    it out to someone like him for the remainder of that period, for less or 
    more, without any unfairness. 

    Shaykh ‘Abd al-‘Azeez ibn Baaz, Shaykh ‘Abd al-‘Azeez Aal 
    al-Shaykh, Shaykh ‘Abd-Allaah ibn Ghadyaan, Shaykh Saalih al-Fawzaan, Shaykh 
    Bakr Abu Zayd. 

    Fataawa al-Lajnah al-Daa’imah 
    (15/92). 

    Shaykh Saalih Fawzaan al-Fawzaan (may Allaah preserve him) 
    said: If a person rents a place for a certain amount of time, he has the 
    right to live in it for that period, or to rent it out to someone else who 
    will use it for a similar purpose, or one that causes less wear and tear, 
    i.e., he may make use of the place himself, or allow someone else to do so. 
    End quote. 

    Al-Muntaqa min Fataawa al-Fawzaan 
    (3/221, question no. 336). 

    But, if the owner has stipulated that you should not rent it 
    out, then you must abide by this condition, because Allaah says 
    (interpretation of the meaning): “O you who believe! Fulfil (your) 
    obligations” [al-Maa’idah 5:1]. 

    And Allaah knows best.
