Malema addressed the party’s memorial service held for Castro in Soweto on Thursday.
He appeared in court last month for making similar remarks in Newcastle and Bloemfontein. Both cases were postponed.
Malema says one of the reasons Cuba is a better country is because Castro took the land and gave it to its rightful owners.
He has called on his supporters to honour him properly.
“That’s the only way you can honour Fidel Castro, take your land because it belongs to you.”
He also used the opportunity to send this message to white people.
