The home side equalized after Ahly captain Ghaly went off with a suspected ruptured knee ligament, as the J-League's leading scorer Hisato Sato netted in the 32nd minute.
Aboutrika, playing at the tournament for the fourth time, scored his fourth goal to go level with record-holders Lionel Messi of Argentina and former Brazil international Denilson.
Ahly also reached the semifinals in 2006, losing to Brazilian side Internacional before winning the third-place playoff against Mexico's Club America.
"The Corinthians are a great team. We'll do our best to get a positive result and dedicate the title to the victims of the Port Said stadium disaster," said the 34-year-old Aboutrika, who was also in the 2006 team.
"Playing with Brazilian opponents is always interesting for me. Also, Brazil is a great thing for me, especially since I dream of reaching the World Cup there with the national team."
Mexican team Monterrey also qualified for the semifinals, setting up a clash with European champions Chelsea on Thursday by beating Asian titleholders Ulsan Hyundai 3-1.
Monterrey, winners of the CONCACAF Champions League last season, took the lead in the ninth minute through 19-year-old winger Jesus Corona while former Argentina international Cesar Delgado added two late goals.
The Korean side scored an 88th-minute consolation through 2012 Asian player of the year Lee Keunho, whose long-range shot eluded keeper Jonathan Orozco.
