The Egypt keeper prevented Mahmoud Shaker from scoring Ittihad's third penalty before netting the last goal, to give Ismaili a 5-3 victory and send their fans into raptures.
Both teams drew 1-1 to send the game into penalty shootout.
Early in the first half, Mohamed Nagi 'Geddo' put Ismaili ahead with a close-range header, connecting with an Abdul-Hamid Hassan cross.
But Ismaili brought the score level in no time after Abdullah Al-Shahat, who was deployed as a left winger instead of the injured Ahmed Samir Farag, came unmarked to release an unstoppable shot from inside the area.
Shortly afterwards, Mohamed Selliti could have been rightfully awarded a penalty kick after he was brought down in the area by keeper Al-Hani Soliman but the referee didn't point at the spot.
Upon wining the game, Ismaili set up a semi-final meeting with Harras Hodoud who defeated Arab Contractors 3-1 on the same day.
