Assalamualikum Sir, please ans my question. I heard that taking bath naked alone in a bathroom is sin in Islam for both men and women. I checked in different sites where I found that it is not sin to take bath naked if one is alone. I am not satisfied by the answer. Sir please guide me the right path. What does Qura'an say about it and in which verses in Al Qura'an is it mentioned.
My second question to you sir is that, will our woudhu be valid if we make it bareheaded for women?

Please answer both of my questions.

Jazakallah khair
