Abrar caused some controversy with his song Parveen. He was criticised by the columnist Javed Chaudry for using the common female Pakistani name of Parveen in an odd way. This followed Chaudhry receiving a letter from a girl name Parveen that related the effects of the song on her life. The girl claimed that she had stopped attending college in Lahore because of harassment from male students. The case was taken to Pakistan's Supreme Court, which ordered Abrar to change the lyrics. He stated that he would abide by the court's decision.
