This comes as the increasing cases of blasphemy in Pakistan continue to be a cause of concern for rights activists.

Pakistan has registered thousands of blasphemy cases, which are mostly against religious minorities like Hindus, Christians, Shia and Ahmadiya Muslims from 1987 till today, according to several reports by rights groups.

A large number of these blasphemy cases in Pakistan are still awaiting justice.
