Ruling on not letting drivers pray in congregation
Question

                What is the shar’i ruling, in your opinion, on people who do not let the drivers who work for them in their houses pray in congregation in the mosques, and tell them to pray at home and do not let them go out unless they – the members of the household – want to go out?
Praise be to Allah.
     What these people should do, who have people working for 
    them in their houses, is to enable them to pray in congregation, because of 
    the great reward and goodness that that will bring. This is a kind of 
    cooperating in righteousness and piety. Allaah says (interpretation of the 
    meaning):

    “Help you one another in Al-Birr 
    and At-Taqwa (virtue, righteousness and piety); but do not help one another 
    in sin and transgression”

    [al-Maa’idah 5:5]

     It is not permissible for them to prevent them from praying 
    in congregation, because praying in congregation is a shar’i obligation, and 
    a shar’i obligation exempts one from work, because obedience to Allaah and 
    His Messenger takes precedence over obedience to any human being. But if 
    this worker is prevented from praying in congregation and he needs his job, 
    then he is excused in this case, because he is being prevented and this is 
    not his choice, rather if he were to leave his work that would cause trouble 
    for him.
