The burqa is a part and parcel of Islamic culture in both India and Pakistan. In my grandmother's generation every woman (except in the villages where women had to work in fields) wore a burqa. In fact even at weddings brides would depart at their rukhsatis in a burqa over their wedding clothes. It was only when they got older they took off their burqas and started wearing a chador.
Though that generation was sufi. The new generation which is reviving the veil is actually bringing in a symptom of salafism.
Veil should be revived, but with a sunni spirit rather than a salafi one.
Many Arab and Indo-Pak ulema do discourage it generally but they do so for proper reasons like the man may not be able to do justice, unlike secularists who discourage it for the sake of westernisation and modernisation.
