Is one sinful for reposting (retweeting) permissible content from a person who has pictures of women or music on their page, if another person enters this person's page through him?

There is no harm in retweeting (reposting) if its content is permissible, and the profile picture on the account is not forbidden, even if the account contains other forbidden matters. Retweeting permissible tweets is not considered assisting in the forbidden things present in the account.
