I own a small computer company. I design accounting software which I sell to
franchised clothing stores. This software allows management to track the arrival and departure times of employees, control the stores' stock inventory and client database.
Some of these stores sell skin-tight shirts and pants. Is this permissible?

From the established principles of Islamic law is that if a commodity can be used for either purpose — lawful and prohibited — then the sin for its prohibited use befalls only the user and there is no blame on the manufacturer or the seller. The owners of the stores selling these commodities are not obliged to ask every woman about her mode of dress because women can wear these clothes at home or under their gowns.

The Ruling

It is permissible to sell these clothing items and deal with those who sell them.
Allah the Almighty knows best.
