The foot (plural feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws or nails.
Neither washing nose is obligatory in Wudhu nor washing mouth. Both of them are just recommended and not obligatory. Washing head or feet in Wudhu is wrong because you should wipe over them and not wash them.
If you are sure that your Wudhu was invalid, you need to perform it properly and re do the prayers which were done with wrong Wudhu.
Unlike Wudu which must have muwalat (successive continuity) ghusl may be done in parts; therefore, you may wash only your head for example, and then come back later to wash other parts of your body. So if you didn't wash a part, you may go back and do it as part of the same ghusl.
May Allah grant you success
Hijab for women is the covering of everything, except for the face and hands. As far as when a woman is praying, she must also wear complete hijab, whether she is in public or she is all alone.
However, our esteemed jurists mention that the feet are exempted from being covered while praying. This means that when a woman is praying, it is not wajib for her to wear socks or cover her feet, unless she is in public or there is a non-mahram male who can see her.
And Allah knows best.
According to the mainstream view of our esteemed jurists, the feet is a part of hijab and it is obligatory for them to be covered, like any other part of a woman's body, with the exemption of her face and hands.
However, in regards to Salat, a woman does not need to cover her feet while she is praying, as long as she is in a place where it is not possible for a non-mahram to see her.
And Allah knows best.
In the name of Allah
Provided that these socks (1) Won't attract the attention of Non-mahram and (2) Do not qualify as Zinah (adornment), they CAN be considered as proper cover for the feet. Otherwise wearing them is in contrast with the meaning and the purpose of Hijab.
Not all your head nor all your feet must be dry when wipe on them in Wudhu. Just part of the front part of the head, and one or more figures must be dry. The wiping must affect that front part of the head and one or more fingers. The affect is not transfer the wetness from the hand to the wiped areas.
Yes it is allowed to expose her feet only , not any part of her leg, if the men who can see her are her own Mahram like father, son, real brother etc. Muslim female must cover her feet even during performing Prayers if any non Mahram man can see her while she is praying.
It does need mentioning that covering the feet is part of compulsory Hijab in front of non Mahram man.
