First-half goals from Payam Sadeghian and Yaghoub Karimi proved enough as Iran made it four wins from four qualifiers, and are now favourites to finish top of Group C.
Meanwhile, Kuwait also secured their place at the finals after beating Qatar 2-0, while Bahrain toiled to a 2-1 victory over bottom side Maldives.
The Kuwaitis are currently second on nine points, and while Qatar and Bahrain can both pull level with them in the final round of qualifiers, a better head-to-head record means Kuwait will definitely progress alongside the Iranians.
The Group C qualifiers will conclude on Tuesday with Bahrain taking on Iran, Kuwait playing Maldives, while Tajikistan lock horns with Qatar.
