Judicial magistrate Jawad Naqvi, who announced the verdict, had been hearing a case filed by Saqib's wife Ayesha Bibi, who said that her husband had married for the second time without getting her permission.
"To get married without your first wife's permission is breaking the law," she had argued in her appeal.
Dawn report adds that Saqib subsequently submitted surety bonds worth Rs. 50,000 to avoid immediate imprisonment. He also has recourse to challenge his conviction.
The Council of Islamic Ideology has often criticised the existing law, which requires written approval from the first wife if her husband wants to marry a second time. (ANI)
