Morsi was forced from office by the army in July and faces charges of inciting violence, Ahram Online reported Monday.
In a statement published Sunday on a Muslim Brotherhood website, the family said, "no matter how much they try to keep him away, the president will not retreat from his calls for a return to democracy, even if his soul is the price."
The statement was released to mark the Islamic celebration of Eid al-Adha.
"The president will not give up by retreating, negotiating or compromising, particularly after all the martyrs, injuries, detainees and missing," it added.
