Hajj & Umrah

Q: Is it permissible for a person to delay his fardh hajj due to his wife being ill?

Q: I’m a male and suffer from male pattern baldness. As a result I’m wearing a wig to only cover the top part of my head, the rest of my hair is my own. 

1. Am I allowed to wear the wig while I perform Umrah? 

2. If not, and I continue wearing it do I have to pay dumm? 

3. How much is the dumm and what do I need to do?

Q: If a husband has already performed his fardh hajj, is it compulsory upon him to take his wife to perform her hajj if she does not have the means for hajj? If he takes her for hajj, will her fardh hajj be fulfilled? 

Q: If a woman has the means to go for her fardh hajj but is not married, can she ask one of her male mahram relatives (e.g. uncle, nephew) to accompany her on the journey?

Q: Can a person apply itr to his body and ihraam clothing before reciting the talbiyah?

A: Before entering into ihraam, it is sunnah to apply itr to one’s body and ihraam clothing. However, after entering into ihraam, it is not permissible.

Q: I am a woman who has always performed Umrah wearing a hat and covering my face. Recently, when I was about to perform Umrah, my sister-in-law insisted that I could wear my niqab directly without the hat, as I would only be wearing it for a few hours, and damm would not be waajib upon me. However, I disagreed with her because I felt that this would compromise the essence of Umrah. 

I believe wearing the niqaab in such a manner involves intentional contact of cloth with the face, which contradicts the principles of ihraam. The allowance for unintentional contact exists, but wearing the niqaab directly seems to me like a deliberate act, done only to avoid the inconvenience of using a hat. 

Please clarify my doubt: 

1. Can I intentionally wear the niqaab directly without a hat and perform Umrah? 

2. Can I wear gloves during Umrah as many Saudi women point out during Umrah that it's haraam?

Q: Can a hernia patient wear underwear in ihraam?
