Is it permissible to buy and sell face masks wholesale, knowing that there are forbidden practices (such as usury and free mixing) in their place of manufacture? Is it permissible to collect delivery costs separately from the product price? Is one sinful if they deliver an order to a woman wearing inappropriate clothing, if they lower their gaze? And is one sinful if the delivery person (mail carrier) will deliver to a woman wearing inappropriate clothing?

Firstly: There is no sin upon you for purchasing from a place that sells some unlawful items if the purchased commodity is permissible, as long as there is no direct assistance in sin.

Secondly: It is permissible to take a delivery fee for the commodity to the buyer, and the buyer must be clearly informed of the value of the commodity and the delivery fee.

Thirdly: It is permissible for the seller to look at a woman's face when dealing with her, solely for identification purposes, without touching or engaging in an unlawful gaze.

Fourthly: There is no sin upon the delivery driver if he encounters someone wearing inappropriate clothing, as the responsibility lies with the one who committed the unlawful act.
