Woman

Bismihi ta'ala
 

Temporary marriage can only be performed with a woman who is from Ahlul Kitab, i.e. she is either a Muslim, a Christian or a Jew. 

If she is of any other faith, or just believes in a supreme being, but does not follow any of the 3 Abrahamic religions, then you cannot do mut'ah with her.

And Allah knows best.

Yes, a Seyid male/female is allowed to marry a non-Seyid male/female. There is nowhere in our religion that somehow forces Seyids/Seyidahs to marry someone like them. This has also unfortunately turned into a very negative culture as well. The esteemed Marja' A.U. Seyid Sistani has pointed to this in a statement where he admonished some parents who cling onto this wrong culture and reject prospect spouses on the basis that they are not Seyids/Seyidahs. 

With prayers for your success.

As far as you are concerned, following the madhhab of Ahlul Bayt (a.s.) is a part of your personality and identity, and your marriage should not obstruct your affiliation to your Shi'i identity. This should be made clear to your fiance. 

In regards to your future children, you as their mother must try to nurture them in such a way where they are aware of their religion and abide to the laws of Islam. Which madhhab they choose is completely up to them, when they become mature and of age. 

If you instill within them the love of religion and the urge to pursue truth and evidence, and allow them to research and read and decide themselves, you've done your obligation.  The rest is for them to decide. 

Your main focus must be on accompanying your husband to be in a noble spiritual way, and avoiding anything that would hurt or harm his understanding of Islam, or your understanding of Islam. 

Be the parents that you should be, and that would be the best thing you can do.

With prayers for your 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.

No, it is not the shar'i responsibility of a male relative to take care of a single female relative after she gets divorced. 

If the relatives wish to do this out of good will, and for the sake of God, then that is a good thing and they will be rewarded for it. Of course, in the case of a woman getting divorced and her not having any immediate family, it is important that her kin support and take care of her and not leave her alone. 

With prayers for your success.

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.

Although there are certain things haram for a woman to do while she is in her menstrual cycle, like pray or recite certain parts of the Quran, but it is still permissible, or rather recommended for her to do worship. 

It is mustahab at times of salat for her to sit at her prayer mat and do dhikr, or recite dua, etc. 

It is also permissible for her to perform sajdah, like sajdah shukr. 

And Allah knows best.

If the father or grandfather are still alive, they are still her shar'i guardian, whether they play a role in her life or not. Unless of course she reaches out to them, and for an unjustifiable reason refuse to give their consent, in such a circumstance the case would be different. 

However, assuming that they are still alive, she must obtain their consent. 

If they have passed, for marriage to be legitimate, she does not need to seek consent, however from a social/moral perspective, she should aim at having family involved, and not pursue an ongoing relationship through a permanent marriage, and not temporary.

And Allah knows best.
