An extensive research on the word Baghaya, with everything a person would need.
Mirza GAQ has used this word in various books:
Following is the index of one particular book, Roohani Khazain volume 16. Under the word ‘Baghaya’, there are three entries. The first entry says:
Baghaya i.e. Street women (Zanaan-e-Baazari) and the loss that they had caused to the country and generation, its narration: pp: 429-432, p.438.
(Because jama’at has taken out the original book from www.alislam.org and replaced it with the book that no more has this index of Vol.16, I have decided to upload it myself. Not a big deal, download here
