On Monday, 10 people were killed in a stampede during looting at a shopping centre in Soweto.
By Wednesday, more than 600 stores had been looted with products worth billions of rand damaged, according to the Consumer Goods Council of South Africa, which called on President Cyril Ramaphosa to impose a state of emergency.
The violence, according to reports, was triggered by the jailing of Mr Zuma on July 7.
Mr Zuma was convicted of contempt after failing to appear before a special commission investigating corruption during his nine-year presidency.
His lawyer argued Monday before South Africa’s Constitutional Court that Mr Zuma should have his sentence rescinded.
Judges on the court said they would consider the arguments and announce their decision at a later date.
