The judge said the case was postponed to June 16. Judge Shaaban el-Shami said the court received the mufti's opinion on Tuesday morning and needed time to discuss it.
The court last month sought the death penalty for Mursi after he and his fellow defendants, including top Brotherhood leader Mohamed Badie, were convicted for killing and kidnapping policemen, attacking police facilities and breaking out of jail during the uprising against then-president Hosni Mubarak.
The court also postponed to June 16 issuing a final ruling in a separate case for Brotherhood leader Khairat el-Shater and 15 others.
Prior to the court announcement, Mursi was seen entering the cage wearing a blue suit and waving to the court.
Mursi has said the court is not legitimate, describing legal proceedings against him as part of a coup by former army chief Abdel Fattah al-Sisi in 2013.
