Is it permissible for women to post pictures of themselves veiled (nothing showing but their eyes) on social media, and what is the ruling if that leads to fitnah?

It is not permissible for a woman to post her picture wearing a niqab on Facebook if her eyes appear in a way that causes temptation or beauty that attracts attention, or if the posture of the picture is eye-catching. Some scholars have explicitly stated the impermissibility of looking at a woman wearing a niqab if her eyes and their surroundings show temptation.
