Friends and family remembered Dumi as a "perfect" man who was creative and versatile. His strong relationship with God was also highlighted throughout the service.
The multi-talented star died on Wednesday last week, following an attempted hijacking. He was shot in the upper body and later died in hospital due to his injuries.
Masilela's wife Simphiwe Ngema was with him during his final moments, comforting him before he was taken to the operating room.
"Dumi was so strong and that's were I'm getting my strength from right now," Simphiwe said at her late husband's memorial service.
Speaking about their relationship with God, she said, "But God is still God. And what comforts me is that I saw God in Dumi. God lived through him."
