With five matches remaining, the defending champions sit third in the standings on 41 points, five behind leaders Zamalek.
Ceramica Cleopatra remain fourth with 39 points.
South African forward Fagrie Lakay put Ceramica ahead five minutes before halftime with a long-range strike, while defender Yasser Ibrahim equalised eight minutes from time.
Ceramica began the match pressing high but struggled to create clear chances, while Ahly gradually took control of possession, with their opponents relying on counterattacks.
Mahmoud “Trezeguet” Hassan tested goalkeeper Mohamed Bassam early on with a powerful effort, but the Ceramica keeper denied him.
Bassam was called into action again to stop a close-range header from Yasser Ibrahim.
Ahly continued to press, with Emam Ashour firing over the bar after a blocked effort fell kindly to him in the 30th minute.
Ceramica took the lead when Lakay fired a powerful long-range shot that Ahly goalkeeper Mostafa Shobier misjudged, allowing the ball to slip through his hands and into the net.
Ahly coach Jess Thorup made an attacking change at halftime, introducing winger Hussein El Shahat for defensive midfielder Alio Dieng as his side pushed for an equaliser.
The Cairo side dominated possession in the second half, but Trezeguet and Marwan Othman missed clear chances.
Thorup then introduced Mohamed Sherif, Achraf Bencharki, Mohamed Ali Ben Romdhane and Taher Mohamed Taher in search of a breakthrough.
Ahly finally found the equaliser when Yasser Ibrahim fired into the far corner from inside the area.
Ceramica substitute Ayman Moka squandered two late chances that could have secured victory.
Ahly had a penalty claim in stoppage time after a handball by Ceramica defender Ahmed Hany, but the referee waved play on following a VAR review.
