Attending prayers in congregation in a mosque where women are uncovered when doing wudoo’
Question

                In our Muslim country at most of the masajid here, when I go for prayer I see some women who enter the masjid after they take off their shoes in front of men. Also when they make wudu’ the fold their sleeves up and uncover apart of their lower legs and stand beside men for wudu’. What should I do? Shall I pray at home and stop going to the masjid? Especially that we are young men and have strong desires.
Praise be to Allah.
    Attending prayers in congregation with the Muslims is 
    obligatory, as we have stated in many answers. See no. 
    8918 and 
    120. You 
    should strive to pray in congregation in a mosque in which the call to 
    prayer is given and you should try to do wudoo’ in your house or place of 
    work. If you have to do wudoo’ in the mosque, then you should lower your 
    gaze and try to keep away from places where women are, because Allaah says 
    (interpretation of the meaning):

    “Tell the believing men to lower their gaze (from looking 
    at forbidden things), and protect their private parts (from illegal sexual 
    acts). That is purer for them”

    [al-Noor 24:30]

    We also advise  believing women to fear Allaah with regard to 
    coming to the mosque. They should realize that they are coming to a place 
    that is one of the noblest places on earth to perform an act of worship that 
    is one of the greatest acts of worship. So it is not befitting for them to 
    disobey their Lord by uncovering that which He has commanded them to cover, 
    and it is not right for her to crowd with men in the place where they do 
    wudoo’. If they cannot find a place to do wudoo’ then they should pray in 
    their homes and that is better for them and brings a greater reward, as it 
    says in Sunan Abi Dawood (570) and elsewhere. It was narrated from 
    ‘Abd-Allaah ibn Mas’ood (may Allaah be pleased with him) that the Prophet 
     (peace and blessings of Allaah be upon him) said: “A woman’s prayer in 
    her house is better than her prayer in hercourtyard,and her prayer in her cabinet is better than herprayer in her courtyard.” Classed as saheeh by al-Albaani in 
    Saheeh Abi Dawood. 

    It says in ‘Awn al-Ma’bood:  

    “A woman’s prayer in her house” means the inner room, as it 
    is more concealing. “Is better than her prayer in her
    courtyard” refers to the area inside the (traditional Arabic) house onto 
    which all the doors of the house open, which is less concealing than the 
    inner room. And “and her prayer in her cabinet” this refers to a small room 
    inside a large house, in which she keeps her precious things such. 

    “better than herprayer in her house” 
    because a woman should be concealed as much a possible.  

    In Sunan al-Tirmidhi (1173) it is narrated from 
    ‘Abd-Allaah ibn Mas’ood (may Allaah be pleased with him) that the Prophet 
     (peace and blessings of Allaah be upon him) said: “Woman is ‘awrah and 
    when she goes out the Shaytaan gets his hopes up (of tempting her and 
    tempting others by her).” 

    Ibn Khuzaymah (1686) and al-Tabaraani (9481) added: “And she 
    is never closer to the Countenance of Allaah than when she is in the 
    innermost part of her house.” 

    Classed as saheeh by al-Albaani in al-Silsilah al-Saheehah 
    (2688). 

    It is not permissible for a Muslim woman to annoy the Muslims 
    by uncovering that which Allaah has enjoined her to cover of her arms and 
    legs. Allaah says (interpretation of the meaning): 

    “O Prophet! Tell your wives and your daughters and the 
    women of the believers to draw their cloaks (veils) all over their bodies 
    (i.e. screen themselves completely except the eyes or one eye to see the 
    way). That will be better, that they should be known (as free respectable 
    women) so as not to be annoyed. And Allaah is Ever Oft‑Forgiving, Most 
    Merciful”

    [al-Ahzaab 33:59]

    She should not crowd with men in their places, or annoy them 
    by mixing with them in a manner that is not permissible or that will cause 
    them hardship. 

    Abu Dawood (5272) narrated from Hamzah ibn Abi Usayd 
    al-Ansaari that he heard the Messenger of Allaah  (peace and blessings 
    of Allaah be upon him) say, as he was leaving the mosque, and men were 
    mixing with women in the street, the Messenger of Allaah  (peace and 
    blessings of Allaah be upon him) said to the women: “Draw back, and do not 
    walk in the middle of the road; keep to the sides of the road.” Then the 
    women used to keep so close to the walls that their garments would catch on 
    the walls because they kept so close to them. Classed as hasan by al-Albaani 
    in Saheeh Abi Dawood.               

    If this is the ruling with regard to walking in the street, 
    when a women is observing complete hijab and wrapping her clothes around her 
    properly, then how about in the case of wudoo’, when the calves and forearms 
    are uncovered? 

    To sum up: You should avoid places of fitnah and mixing as 
    much as you can, and choose for yourself the mosque where it is least likely 
    that women go or uncover their ‘awrahs there. Try to do wudoo’ in your 
    house, and avoid places of fitnah. 
And Allaah knows 
    best.
