This new force-marriage campaign is being run in most of the areas in the Pakistan's troubled NWFP through regular announcements made in mosques to congregations.
The incident have come into light offlate as some women protesting against such a dictum approached the authorities to seek justice.
Salma, who teaches in a primary school in Peshawar, told the Dawn newspaper that Taliban have told families to declare in mosques if they have unmarried girls so that their hand could be given in marriage, most probably to militants.
If they did not do so, the girls would be forcibly married off, the newspaper quoted the 30-year-old widow as saying.
She also said the Taliban in the Swat valley of NWFP have threatened women with dire punishment, if they are found outside their homes without identity cards and a male relative accompanying them.
Couples should also carry 'Nikah Nama' or marriage certificates with them when they venture out of home or they will be in trouble, she said.
"I have heard that Taliban have announced that if a girl above the age of seven is found outside her house, she would be slaughtered," Salma said.
