Can she take off her Hijab in front of people who have learning difficulties?
Question

                I work in care home with people who have learning disabilties. both men and woman. sometimes i take my hijab off in their presence, is this permissible?.
Praise be to Allah.
      Firstly: 

    It is obligatory for a woman to cover all of her body in 
    front of non-mahram men. See the answer to question no. 
    11774. 

    She should not speak to non-mahram men except in the case of 
    need, without softening her voice, as Allah says (interpretation of the 
    meaning):

    “then be not soft in speech, lest he in whose heart is a 
    disease (of hypocrisy, or evil desire for adultery) should be moved with 
    desire, but speak in an honourable manner”

    [al-Ahzaab 33:32]. 

    Secondly: 

    The basic principle is that it is obligatory to wear Hijab in 
    front of all non-mahram men. That includes those who have learning 
    difficulties, except those who have developmental delays which mean that 
    they do not understand about women and have no inclination or desire towards 
    them. Such a person comes under the same heading as “old male servants 
    who lack vigour” [al-Noor 24:31]. So a woman may uncover in front of him 
    what she in covers in front of her mahram, which is usually what appears of 
    her, such as the head, face, forearms and feet. 

    But if he understands about women and feels inclination 
    towards them, then he is like any other man and she must observe hijab in 
    front of him.
Ibn Qudaamah (may Allah have mercy on him) 
    said: Whoever no longer feels any desire, because of old age, impotence or 
    incurable illness, or because he is a eunuch, … or a mukhannath (the 
    effeminate man or a man who has female hormones) who feels no desire, the 
    ruling that applies to such a man is the same as the ruling that applies to 
    mahrams regarding looking at women, because Allaah says (interpretation of 
    the meaning): ‘… or old male servants who lack vigour…’ [al-Noor 24:31], 
    i.e., those who feel no desire for women.” Ibn ‘Abbaas said: “This is the 
    one of whom women do not feel shy.” He also said: “This is the mukhannath 
    who is impotent (i.e., cannot have an erection).”
It was reported that Mujaahid and Qutaadah 
    said: “This is the one who has no interest in women, but if he is a 
    mukhannath who feels desire and knows about women, then the rules that apply 
    to others apply also to him, because ‘Aa’ishah said: ‘A mukhannath entered 
    upon the wives of the Prophet (peace and blessings of Allaah be upon him), 
    and they used to think that he was a man who felt no physical desires, but 
    the Prophet (peace and blessings of Allaah be upon him) entered upon us when 
    this man was describing a woman and saying ‘When she comes in, she comes on 
    four, and when she goes out, she goes on eight.’ The Prophet (peace and 
    blessings of Allaah be upon him) said: ‘Do I not see that this man knows who 
    is here? This one should never enter upon you.’ And he was kept away after 
    that.” (Reported by Abu Dawood and others).

    Shaykh Ibn Jibreen (may Allah have mercy on him) was asked 
    about an adult person who is developmentally delayed: do women have to 
    observe hijab in front of him? 

    He replied: If the developmental delay is severe, in the 
    sense that he cannot think or understand, and he does not know what things 
    mean and he has no desire that may prompt him to look and touch and so on, 
    and he has no interest in women, rather he is like a child or less than 
    that, then there is no need to observe hijab in front of him, and he is 
    included in the words of Allah (interpretation of the meaning) “old male 
    servants who lack vigour” [al-Noor 24:31]. But if he understands some of 
    these matters and he has an inclination towards women, and it is clear from 
    what he says that he feels desire, then he should not be allowed to enter 
    upon women and they have to observe hijab in front of him, because of the 
    story of the mukhannath who said to the brother of Umm Salamah: If you 
    conquer al-Taa’if, I will show you the daughter of Ghaylaan, for she comes 
    on four (folds of fat), and goes on eight. The Prophet (blessings and peace 
    of Allah be upon him) said: “I think that this man knows what’s what. This 
    one should never enter upon you.” Narrated by al-Bukhaari and others. And 
    Allah knows best.

    Thirdly:  

    Attention must be paid to the prohibition on being alone with 
    this non-mahram who is of sound mind; rather attention should be paid to the 
    prohibition on working in mixed environments. Please see the answer the 
    questions no. 45905 and
    1200. 

    We ask Allah to help and guide you. 

    And Allah knows best.
