Is it permissible for him to accept zakaah when he has property that is rented out?
Question

                There is a man who is retired from work and he has a house in which he and his children live, but he does not have any income apart from two apartments he owns that he rents out, and that is not sufficient for his and his children’s needs. Can he be given zakaah?.
Praise be to Allah.
      It is permissible to give zakaah to one who does not have 
      enough for his maintenance, even if he has property that he rents out, 
      because this is a case of one who is needy (miskeen) and is mentioned in 
      the verse in which Allah says (interpretation of the meaning): 
      “As-Sadaqaat (here it means Zakaah) are only for the Fuqaraa’ (poor), and 
      Al‑Masaakeen (the poor)…” [al-Tawbah 9:60]. Al-Nawawi (may Allah have 
      mercy on him) said: The miskeen (poor, needy) is the one who is able to 
      acquire money or income to meet some of his needs but it is not enough for 
      him. End quote from al-Minhaaj ma‘a Sharhihi Mughni al-Muhtaaj, 
      4/176. 

    And Allah tells us in the story of Moosa (peace be upon him) 
    with al-Khidr about the poor and needy people who owned a ship. Allah says 
    (interpretation of the meaning):

    “As for the ship, it belonged to Masaakeen (poor people) 
    working in the sea…”

    [al-Kahf 18:79].

    They did not cease to be regarded as miskeen even though they 
    owned a ship.

     Based on that, if he has accommodation that he rents out, 
    but what he gets from it is not sufficient for him, it is permissible to 
    give zakaah to him, because he is included in the verse which describes the 
    categories of people to whom zakaah may be given. 

    Imam Maalik (may Allah have mercy on him) said: If a person 
    has a house and servant and nothing else, he may be given zakaah. 

    End quote from al-Mudawwanah, 3/221 

    Al-Nawawi (may Allah have mercy on him) said: If he has 
    property but the income from it is less than is sufficient for him, then he 
    is faqeer or miskeen [poor or needy] so he may be given zakaah to ensure he 
    has sufficient to live on, and he should not be made to sell his property.

    End quote from Sharh al-Muhadhdhab, 6/174 

    In Kashshaaf al-Qinaa‘ (2/273) it says: Imam Ahmad 
    said according to the report of Muhammad ibn al-Hakam: If he has a farm or 
    property that he rents for ten thousand or more, but it is not enough for 
    him, he may receive zakaah. … End quote. 

    To sum up: If a person has property that he rents out, but 
    what he gets from it is not sufficient for him, it is permissible to give 
    him zakaah to make up what he has, so that it will be sufficient for him and 
    for those on whom he spends, such as his children, wife, father and mother. 

    And Allah knows best.
