Query: Brother Pimping backround music is a ripoff

The background music of Brother Pimpin (track #11) belongs to an Egyptian musician. I used to listen to that tune years ago when I was a kid growing up in the Middle East. I thought that some credit would be given to that artist, but none was to be found in the JAY-Z's CD. Isn't it illegal for an artist to do that? Or at least a credit should have been given to the Egyptian artist. I just thought that this was just a rip off.
