Rabada bowled Root for 27 before following through just in front of the England captain, pumping his fists and roaring in celebration.
He was fined 15 percent of his match fee and picked up a demerit point – taking his tally to the threshold of four in a two-year period.
“I have every belief in anyone who is going to come into my spot, that they have the potential to knock anyone over,” Rabada added.
“I guess it gives me a chance to work on my game, and gives me a chance to have a bit of a rest.”
England take a 2-1 series lead into the decisive match after they won the third Test by an innings and 53 runs.
