What is the ruling on participating in a social media contest that requires photographing and displaying women's sleepwear in bedrooms for evaluation, and what is the ruling on that if the displayed clothes are of other types, and is that considered a violation of the sanctity of the home or the husband if done without his permission?

Photographing women's sleepwear and displaying it to a group of women, away from men, is permissible as long as it does not lead to corruption. However, photographing a bedroom or parts of it without the owner's permission is not permissible, because the basic principle is that it is not allowed to intrude upon other people's homes without their permission. The Messenger of Allah (peace be upon him) said: "Verily, permission (to enter) was ordained for the sake of the sight (not to look at private things)."
