Muslim Brotherhood Spokesman Ahmed Aref said on Sunday that the group’s response to any initiatives "depends on the return of constitutional legitimacy". 

Aref told Al-Jazeera that the Brotherhood differentiates between the Azhar as an institution and its imam, Ahmed al-Tayeb, who he accused of supporting the “coup”, the state news agency reported. 

Tayeb's deputy, Mohamed Mehana, has revealed that so far no contact has been made with the parties expected to attend the meeting. 

Egypt’s Azhar, the most prestigious Islamic institution, announced that it would convene different factions after Eid holidays to discuss possible scenarios to end the current political crisis.  

A new political crisis erupted in the Middle East's most populous country after the army ousted Islamist President Mohamed Mursi in response to mass demonstrations last month.
