On 19 April 2018, fellow singer Meesha Shafi accused Ali Zafar of sexual harassment on Twitter. Ali Zafar categorically denied the allegation and said that he would take the matter to court. On 23 June 2018, Ali Zafar filed a 1 billion rupees defamation case against Shafi for slander under the Defamation Ordinance 2002, claiming that Shafi had caused "tremendous injury" to his "reputation, goodwill, livelihood" through "false, slanderous and defamatory" allegations, according to Geo News. The suit read: "As the defamatory statements are patently false, it can only be concluded that this malicious campaign has been launched against the plaintiff as part of a motivated conspiracy to tarnish the plaintiff's good image through making false accusations.
