Hosts Production took the lead through defender Hazem Fathi in what proved to be a highly-dubious goal.
Abdullah Al-Saied leveled with a trade-mark freekick as referee Medhat Al-Houfi sent two Production players off, including the keeper, in the final 15 minutes.
It is an impressive start for new Production manager Mohamed Helmi, with the military side only claiming their second point in seven previous meetings with Ahly.
Al Ahly missed out on moving top as they remained second behind leaders Harras Hodoud, while Production are third from bottom.
