A friend of mine posted on FB that Nelson Mandela advocated for and practiced white genocide. Is he right?

Hey, like title says. I think he's completely wrong, I can't find anything like that that says he did or even said such a thing. I think what my friend is doing is just sharing a view he now has because he read that somewhere or he's confusing and misinterpreted exactly what was going on in the apartheid era of South Africa and Mandela's role in it.

If im wrong and he's right could you provided links for me please? Thank you!
