What is the Sharʿī ruling on one who sees the differing opinions of the jurists regarding the ruling on looking at pictures that include ʿawrah, and bases this on what has been narrated from some jurists that looking at a picture of a woman's ʿawrah in water or a mirror is not forbidden, unlike direct viewing?

Scholars have differed on the prohibition of looking at a woman's awrah (private parts) in a mirror or in water, but they have agreed on the prohibition of anything that leads to fitnah (temptation/strife). Therefore, if looking is with lust or leads to fitnah, it is not permissible, because looking at the awrah in a mirror brings fitnah, except out of necessity. It has not been reported that looking at a woman's private parts or touching them with lust makes her permanently forbidden for marriage. Perhaps the questioner is referring to what the Hanafis stated about the permanent prohibition of a woman's ascendants or descendants for someone who looks at her private parts with lust.
