He was given some charity that was came from riba-based wealth; can he go for hajj with it?

If a person is given some charity by someone who deals in
riba, there is nothing wrong with him using that money to go for Hajj, and
there is no sin on him if he accepts what is given to him, because the sin
of riba is borne by the one who engages in it. As for the one who takes it
in a manner that is approved of in sharee’ah, such as by being given it as a
gift or a charity, there is no sin on him.  

The evidence for that is the fact that the Messenger
(peace and blessings of Allaah be upon him) accepted gifts from the Jews,
and he ate the food of the Jews, and bought from the Jews, even though the
Jews are known for dealing in riba and consuming haraam wealth. 

Yes, if we assume that someone steals a sheep from a man’s
flock and comes and gives it to him, then in that case it is haraam, because
you know that this sheep does not belong to him. But if he was dealing in
riba, then his sin is on himself, and whoever takes it from him in a manner
that is approved of in sharee’ah, it is permissible for him. So we say to
this woman: there is no sin on you if you go for Hajj with the money that
has been given to you by one who is known to deal in riba. End quote.
