Abu-Jamal has been on death row since 1982, when he was convicted of killing a Philadelphia policeman.
The decision came amid a hearing on whether Abu-Jamal has a right to a new trial. Abu-Jamal contends that he was framed for the 1981 murder, and that he did not receive fair treatment at his original trial.
Judge Albert Sabo said he granted the stay because higher courts would not have the time to review Abu-Jamal's case before the scheduled August 17 execution date.
The stay of execution is indefinite, which will allow Abu-Jamal to pursue an appeal. He remains on death row.
While in prison, Abu-Jamal has continued his journalism activities, most recently with his book Live From Death Row.
