Fathwa, - Proofs for the permissibility for a woman to show her feet

Question:
Could you please provide me with evidence on why it is permissible for
a woman to show her feet. There is evidence in the hadith about
showing the hands and face, but I have not seen any regarding showing
the feet.
Answer:
Assalamu alaykum
Assalamu alaykum
In the name of Allah the Inspirer of truth.
The reason the feet are also exempt from being covered during salat is
that they has been considered as "that which is normally revealed
thereof" in the following verse of the Qur'an:
"She should not display her beauty except that which is revealed
thereof" (Sura Nur).
The scholars of the Hanafi school have considered that the feet are
also exempt just like the face and hands for the following reasons:
(1) they can easily become uncovered while walking (even if the women
is wearing a long garment), especially in the case of poorer people
(who may not have the means to possess socks) and (2) if the face,
which is more a place of attraction, is exempted by this verse then
more conclusively the feet should also be exempted. Furthermore, there
is nothing categorically related that makes them out to be part of
theawra.
Having said this, covering them in salat to observe the etiquette of
the difference of opinion with other schools who consider them part of
theawra, though not necessary, would be a worthy deed. Likewise, it is
more preferable to have them covered to minimize attraction.
And Allah knows best.
