I was just told by an Indian friend that Pakistani people marry their cousin's, is this true?

Marriage is different from region to region and religion to religion. From what I know Pakistanis do not do that. But many Muslims tend to to keep money and land in the family. As for me and probably 90% of the new Muslim generation sees it is that we would never do that. But, I don't see it as a bad thing. Just not a thing to do unless you need to. But, just be mutual. Don't go around hating Pakistanis. I love them, they can be great people. Many tribal places in Pakistan didn't always have leave there area. So they did marry cousins. Same with Arabs, and Africans, etc.
