Azad went to cast his vote at the DPS polling station at Jogi Gate area, but was refused permission by the presiding officer who demanded his identity proof.
The matter was later settled when a local Congress leader went to stand surety for Azad's identity.
Bharatiya Janata Party leaders too said Azad is a senior national level leader and they did not dispute his identity.
Azad is himself fighting the elections from Udhampur Lok Sabha seat although he is registered as voter in Jammu.
Talking to media persons after casting his vote, Azad said: "The BJP has lost all hope and in frustration they are raking up issues like the abrogation of Article 370, Ram Mandir etc."
