Ruling on the money that a lawyer gets for defending a drug dealer
Question

                There are two people who were arrested for possessing drugs and hasheesh, then a lawyer got them out and had them found innocent of this crime, although their crime was as clear as the light of day and the accusation against them was clearly proven. 

My question is: 

What is the ruling on this money that the lawyer got for getting them out?.
Praise be to Allah.The ruling 
    on practising law has been explained in a fatwa quoted in the answer to 
    question no. 9496. We stated there that it is haraam for lawyers to protect 
    evil and defend those who do evil, and that this comes under the heading of 
    cooperating in sin and transgression, which Allaah has forbidden as He 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]
Based on 
    this, the lawyer who defended these evil dealers who spread mischief in the 
    land by selling haraam drugs has to repent to Allaah, may He be exalted, 
    from this action. He should hasten to advise those evildoers not to follow a 
    path that will let them escape from the punishment they deserve. He has to 
    go back before the judges and retract his defence, if it is not too late, 
    and he should not agree to carry on with them if there is any appeal against 
    them. 
With regard 
    to the money that he has taken from them, it is haraam wealth, because he 
    took it in return for a haraam deed. Hence as well as repenting, seeking 
    forgiveness and resolving not to do this again, he has to hasten to get rid 
    of this wealth, by spending it on charitable causes. He should remember that 
    the Prophet  (peace and blessings of Allaah be upon him) said: “The one 
    who repents from sin is like the one who did not sin at all.” He should also 
    note that by doing that he will purify his permissible wealth, because if he 
    keeps the haraam wealth, that may lead to the destruction of the permissible 
    wealth that he has. It is not permissible for him to give it back to those 
    dealers. We ask Allaah to compensate him with something better than it. 
And Allaah 
    knows best.
