Can the hadith about men's and women's ablution together during the time of the Prophet, peace and blessings be upon him, be used as evidence for the permissibility of a woman uncovering her hair, face, forearms, and feet in front of a man?

Scholars have differed on the interpretation of the Hadith narrated by Abdullah ibn Umar: "We, men and women, used to perform ablution during the time of the Messenger of Allah, peace and blessings be upon him, from a single vessel, into which we would dip our hands," presenting three views:

The first: That the Hadith does not imply men and women gathering at the same time for ablution, but rather states that their ablution place and water source were one, and they took turns using it.

The second: That the women referred to are wives and unmarriageable kin (mahārim), based on Al-Bukhari's heading: "Chapter on a man's ablution with his wife."

The third: That the Hadith describes an event that took place before the فرض الحجاب (imposition of hijab), and after its imposition, it applies exclusively to wives and unmarriageable kin.

The answer concluded that Islamic law does not permit a woman to uncover her forearms, shins, or head in front of non-mahram men. This is supported by the fact that Umar ibn Al-Khattab punished those men and women who gathered in one place for ablution and ordered the allocation of a separate place for men and another for women.
