Ahly had the better possession in the first half but could not threaten ENPPI, who were dangerous on the break.
Substitute Vincent Die Foneye broke clear after taking a perfectly threaded pass and his low cross was converted by sweeper Rabeia into his own net.
Manuel Jose made a triple substitution after the goal, bringing in Walid Soliman, Fabio Junior and Abdullah Al-Saied for Ahmed Shedid, Mohamed Abou-Treika and Mohamed Fadl.
But the Reds remained out of sorts, with the stands almost empty without the usual passion of the Ultras Ahlawy fans.
Debutant Al-Saied had a chance to pull off a memorable equalizer with a freekick in injury time, but the set-piece specialist hit the ENPPI wall.
