The match was marred by the fans’ clashes in the stands at the Azadi Stadium.
Two teams showed a lackluster performance in front of about 80,000 spectators.
Tractor Sazi earlier on the day suffered its third defeat in a row, losing to Zob Ahan 2-0.
Vahid Mohammadzadeh gave Zob Ahan the lead in the 16th minute from the penalty spot and Mehran Derakhshan Mehr was on target at the added time.
Struggling Sepidrood was also defeated against Foolad 2-1 in Ahvaz.
On Saturday, Esteghlal will face Padideh in Mashhad and is hoping to close the six-point gap with Persepolis.
