The Libyan giants delivered a dominant performance at Tripoli Stadium, scoring four goals in each half to record their second consecutive league victory.
Former Wydad Casablanca winger Muaid Ellafi opened the scoring in the seventh minute with a volley from a cross before Hamdou Elhouni doubled the advantage with an acrobatic finish in the 21st minute.
Congolese striker Fiston Mayele extended the lead four minutes later, finishing a cross from Ellafi to make it 3-0.
Mohammed Khalil added the fourth goal in the 37th minute with a header, sending Al Ahli into the interval with a commanding 4-0 advantage.
The hosts maintained their attacking intensity after the restart, with Ezoo El Maremi making it five in the 58th minute through an excellent backheel finish.
Elhouni completed his brace eight minutes later, scoring Al Ahli's sixth goal after another impressive attacking move.
South African forward Fagrie Lakay added the seventh in the 70th minute before Burundi international Jean Claude Girumugisha completed the rout in the 82nd minute.
The result underlined Al Ahli Tripoli's attacking strength following an impressive recruitment drive ahead of the new campaign, with several high-profile additions strengthening their squad.
Al Ahli maintain winning momentum
The victory takes Al Ahli Tripoli to six points from their opening two league matches, following their 2-0 away win over Al Bashaer on 28 October.
The team have also enjoyed an impressive run in the CAF Confederation Cup qualifying campaign, defeating KMKM of Zanzibar 7-0 on aggregate before overcoming Ethiopia's Wolwalo Adigrat University 8-1 in the final qualifying round.
Al Khums, meanwhile, suffered another disappointing result and remain without a point after three consecutive league defeats.
Al Ahli Tripoli will look to continue their winning run when they host Al Shomooa in their next league fixture on Friday, 6 November.
