Abdolali’s lawyer says the execution, which was scheduled for Wednesday morning, has not been carried out.
Abdolali was earlier moved to solitary confinement in a prison in Karaj in preparation for his death sentence to be carried out.
This is the third time that the 25-year-old’s planned hanging is stopped.
Arman was 17 when he was arrested for the murder of Ghazaleh Shakour.
He was sentenced to death in 2015 a year after Shakour disappeared. Her body has never been found.
Many Iranian celebrities have called on the judiciary to grant him a stay of execution.
