An Al-Azhar source has said that contacts were ongoing with political powers, including MB leaders, over a proposed national initiative to resolve the political impasse.
"We have not asked for Al-Azhar intervention," Brotherhood leader Saad al-Husseini told Anadolu Agency on Thursday.
"However, we welcome any effort or mediation by any party to prevent bloodshed, as long as it is based on the return of legitimacy," he added, referring to the group's demand for the reinstatement of ousted president Mohamed Morsi.
Former youth minister Osama Yassin also denied reports of talks between the Muslim Brotherhood and Al-Azhar.
He stressed that any initiative aimed at resolving the crisis "should be based on respect for legitimacy, not the coup."
Egypt has been in the throes of deep political crisis since Morsi's ouster by the army last month following mass protests against his regime.
Since then, thousands of pro-Morsi demonstrators have been staging daily protests and sit-ins to denounce what they describe as a "military coup" against the elected president and demand his reinstatement.
Al-Azhar, meanwhile, has called for dialog "as the only means of achieving real national reconciliation."
Yassin, however, asserted that the proposed dialog initiative "merely aims to legitimize the coup."
