Is it true that there is a jurisprudential opinion which holds that a man's 'awrah in front of a woman is his entire body except for the face and hands?

None of the scholars explicitly stated the obligation for a man to cover his entire body from women. Rather, their discourse on defining a man's awrah (intimate parts) is confined to the area between the navel and the knee.

Scholars have differed on the limits of what a woman is permitted to look at from a non-mahram man, and this is based on several opinions:

1. First Opinion: It is permissible for a woman to look at anything of a non-mahram man except his awrah (what is above the navel and below the knee). They cited incidents from the Sunnah and a rational argument that absolutely prohibiting women from looking at men would necessitate men wearing hijab, and that women used to attend prayers with the Messenger of Allah, peace be upon him. 2. Second Opinion: The ruling on a woman looking at a non-mahram man is the same as the ruling on a man looking at his mahrams. Thus, it is permissible for her to look at a man as much as it is permissible for him to look at his mahram women, and it is forbidden to look at anything beyond that. 3. Third Opinion: The ruling on a woman looking at a non-mahram man is the same as the ruling on his looking at her. Therefore, it is not permissible for her to see of him except what is permissible for him to see of her (the face and hands, when there is no fear of fitna). They cited the verse about lowering the gaze and the hadith of Umm Salamah and Ibn Umm Maktum, and a rational argument that the reason for prohibiting looking is the fear of fitna, which is present when a woman looks at men. 4. Fourth Opinion: It is disliked (makrooh) for a woman to look at a man's face, hands, and feet, but it is not forbidden (haram) for her. However, it is forbidden for her to look at anything beyond that.
