Eating iftaar with one whose wealth is haraam
Question

                Should we accept the Aftar which is given by a person who is getting almost HARAM money.
Praise be to Allah.If most of the man’s wealth is haraam, then it is permissible to accept his invitation. 
The Prophet  (peace and blessings of Allaah be upon him) accepted invitations 
    to meals with the Jews, even though Allaah had described them as consuming riba (usury) and consuming the people’s wealth unlawfully. One of the 
    salaf said concerning such cases: It is a gain for you and his sin is against him.  
It is also permissible for you not to accept his invitation as a rebuke to him for 
    his haraam earnings. This is preferable if that will make him give up the evil that he is doing. 
And Allaah knows best.
