What is the ruling on posting a picture of an unveiled woman on a website for selling women's clothing in European countries? Is this considered an ongoing sin? And what is the appropriate answer to the company in case it is not permissible?

It is not permissible to upload a picture of a woman who is immodestly adorned to websites, because it serves as a means for looking at her and leads to sin. If the questioner knows that the website will publish pictures of immodestly adorned women, then it is not permissible for him to design it in the first place. He must seek forgiveness, repent, and refuse to publish such pictures. As for the issue of "ongoing sin," whoever calls for an evil or commits a sin and people follow him in it, he bears its sin and the sin of those who followed him, unless he repents with sincere repentance, in which case the sin is cut off from him.
