The presiding judge in the trial asked the mufti – the country's official interpreter of Islamic law – to consider death sentences for the six codefendants, saying the court would convene again on June 18 after the mufti's response.
It will then pronounce its verdict and sentence for the remaining five defendants, including Morsi, on charges of having supplied Qatar with classified documents, AFP reported.
Egyptian law requires the mufti to sign off on death sentences. His opinion is not binding but is usually respected by courts.
Qatar was a main backer of Morsi and his Muslim Brotherhood movement while he was in power between 2012 and July 2013, when the military overthrew and detained him.
He has already received sentences in three separate trials.
He has been sentenced to death for his alleged role in prison breaks and attacks on police stations during the 2011 uprising that overthrew veteran strongman Hosni Mubarak.
The Qatar espionage case stems from allegations that aides passed on classified state secrets to Doha using intermediaries.
The six facing a death sentence include Ibrahim Mohamed Hilal, whom the prosecution had identified as a senior editor with the Qatar-based channel Al-Jazeera.
