Ihraam for women

Q: I wear a wig due to baldness. I am proceeding for Hajj. Please tell me if I am allowed to wear the wig under my hijab for ihraam. 

Q: I performed umrah some years back with my face covered such that veil was touching my face. I remained in ihraam for less than a day. Am I supposed to give sadqa or damm? Please explain what's the difference between these two?

Q: Kindly advise us about ihram purdah. We are leaving for umrah in one days time and really in need of naseehat as some people who are studying deen advise that the sin is great if purdah touches the face, so rather not wear. Whilst another person who frequents haram sharief says that ihraam purdah was only introduced recently by the conserved Indian ulama and yet another apaa says that wear a normal purdah and pay dum.We want to wear the ihraam purdah. What is the dum? And can we please be advised regarding purdah in Haram Sharief whilst in ihraam?

Q: My mother requests a fatwa to show some women regarding the purdah in ihram, explaining:

1. The cloth should not touch the face

2. Purdah has to be observed from ghayr mahrams.

There is a misconception amongst some women who, throughout the year observe purda, اَلْحَمْدُ لِلّه, but due to a certain aalim's wife informing them that purdah is not necessary in ihraam, they discard it during umrah. She also would like to find out from Hazrat that:

3. Is wearing a normal purdah intentionally a major sin?

4. Would this also be the case if out of circumstances, since due to her eyesight, she cannot see with the cap purdah clearly?

5. What would be the penalty if the cap purdah unintentionally touches the face?

Q: If wearing the cap purdah in ihraam is difficult, should a woman wear the normal purdah or not wear any? Some are of the opinion of wearing the normal purdah and removing before 12 hours, is this also a correct view?

Q: A female scholar in Masjid Nabwi told my wife that it is permissible to cover the face while doing Umrah and that there is no proof for covering the face while doing umrah. She followed her instruction and did umrah while her face was covered with niqaab. Was the female scholar correct? Does my wife have to pay any type of compensation?

Q: Is it permissible for a female to wear a normal niqaab when performing umrah, or does she have to keep her face uncovered while in ihraam? The cap purdah is very difficult to use. 

Q:

1. My wife did umrah with her niqab on (not the one with the cap portruding but the regular). What should be done now?
2. Someone says that if you did umrah, it is not fard to do hajj, even if you are finnacially capable. Please clarify if it is true?

Q: What should a female do if her period commences during the hajj or while she is on the way for hajj?

Q: I am a doctor working in Makkah Makkarrarmah and living here with my family since 2 years. Every time we come from pakistan we perform umrah from the meeqat. 3 days before I came from pakistan, I made niyat for umrah and ihram from the airport and when I reached Makkah my peroids came. So now what should I do?
