In asia countires, People have kamati/kaymati (sound : committee), in which everyone put in certain amount for certain time of period and every month, each member get money. There is someone who has shady business (to what I know is they avoided huge tax on imports).
My question is, because each month a member get total amount of money collected from each member, with that member included in it and her source of income was avoidance of tax or selling drugs, does it make the member who took thier turn haram money?
