Can he work as a typist in a law office that defends criminals?
Question

                Can I work as a typist in a law office, where as far as I know the lawyers defend criminals and I type up reports for them on the computer? Is there any sin on me for that?.
Praise be to Allah.Working in 
    the field of law may be permissible or it may be haraam, depending on the 
    situation. If the lawyers support those who have been wronged and strive to 
    have their rights restored, then it is permissible, and even mustahabb. But 
    if it is to support falsehood and help in wrongdoing, and is based on 
    telling lies and giving false witness, then it is haraam. See also question 
    no. 9496. 
The ruling 
    on working in law offices, whether typing or anything else, is to be based 
    on the principle stated above, because typing is something the lawyers need. 
    If the lawyer’s work is permissible, then the means that help with it are 
    also permissible, and vice versa. 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. And fear Allaah. Verily, 
    Allaah is Severe in punishment”

    [al-Maa'idah 5:2]
If you know 
    that the lawyers are defending criminals, and you are asked to type up their 
    reports, it is not permissible for you to do that, because that is helping 
    in sin and approving of evil. The Prophet  (peace and blessings of 
    Allaah be upon him) said: “Whoever among you sees an evil action, let him 
    change it with his hand (by taking action); if he cannot, then with his 
    tongue (by speaking out); and if he cannot, then with his heart (by hating 
    it and feeling it is wrong), and that is the weakest of faith.” Narrated by 
    Muslim (49). 
Defending 
    criminals, covering up for them and supporting them is a transgression 
    against the rights of the ummah, because the spread of crime and the lack of 
    punishment have bad consequences as is obvious, and it is a crime against 
    the victim in cases that have to do with specific individuals. 
Any kind of 
    help to do wrong or commit crime is haraam, whether it is by preparing 
    materials, typing them up, defending them, etc. 
What you 
    have to do is advise these people, and refrain from typing up anything that 
    you know is defending falsehood.  If they respond, all well and good, 
    otherwise look for another job which is free of sin and through which you 
    may earn halaal provision. 
We ask 
    Allaah to guide us and you. 
And Allaah 
    knows best.
