JDT took the lead in the 20th minute through Brazilian import Jairo da Silva in the match played at the King Abdullah Sports City Stadium, Bernama reported.
However, despite going down to 10 men, Al-Ahli delivered a more dominant performance, controlling much of the game and creating several dangerous chances.
The Saudi giants, who are ACLE defending champions, then equalised through Franck Kessié, who headed in a corner during first-half stoppage time.
In the second half, Al-Ahli had several attempts at goal before Galeno put them ahead in the 54th minute with a powerful strike from outside the penalty box that beat JDT goalkeeper Andoni Zubiaurre.
The Malaysian Super League champions attempted to mount a comeback by bringing on Bergson da Silva in the 75th minute to bolster their attack, but failed to find an equaliser.
The result means Al-Ahli will face Japan’s Vissel Kobe in the semi-finals after the latter defeated Qatar’s Al Sadd 5-4 on penalties in another quarter-final match.
