Is it permissible to accept a job offer to create an e-commerce platform for selling clothes, with the possibility of displaying pictures of women without hijab to promote the products?

Designing a website for selling clothes is not ruled to be unlawful, because the primary purpose—which is selling clothes—is permissible. Any incidental display of images of unveiled women is a secondary, unintended consequence. "What is tolerated implicitly in a matter is not tolerated explicitly." The selection of images is not the responsibility of the website designer but of the sellers, and a person is only responsible for their own actions and is not questioned about the actions of others, as Allah the Almighty said: "And whoever earns a sin only earns it against himself," and "O you who have believed, upon you is [the responsibility for] yourselves. Those who have erred will not harm you when you have been guided," and "You are not charged except [with responsibility for] yourself."
