Is it permissible to teach women Quranic recitation via video call in which their images appear with a female teacher, and would there be a sin if someone spied on this call, or if the images of the women were seen by a male official, knowing the possibility that some of them might not adhere to the full شرعي (Sharia-compliant) hijab during the call?

It is permissible for a woman to learn the Qur’an from a female teacher via reliable communication programs, and it is preferable to limit it to audio only.

It is not permissible for an official or a visitor to view unveiled women's pictures, nor is it permissible to photograph women in the first place, due to the temptation involved, and because the picture will be saved and there is no guarantee that others will not view it. Sheikh Ibn ‘Uthaymeen was asked about the ruling on photographing a bride, and he stated that it is forbidden.
