Those people upon whom Hajj is compulsory

Woman selling her gold to go for Hajj

Q: A women in her near 60's is diabetic, has blood pressure issues and foot corn such that if she walks much she get's pain in her legs. 

Now when she was married many years back, she was gifted some gold such that if that is sold she can pay for hajj. Initially she didn't do so. Now, she can only do hajj by selling the gold. She doesn't earn otherwise. Would hajj be fard on her?

Postponing hajj due to the fitnahs in the haramain

Q: There is a lot of fitnah happening in Saudi Arabia; the government is allowing a lot of haraam there. The Hajj is being used by the government to extort money from Muslims. Muslims are committing a lot of haraam near the Kaaba; there are reports of men touching women's buttocks during the circumambulation of the Kaaba. Many are taking photos inside the Hajj to the point where it's almost impossible to avoid being recorded. 

Would it be permissible to postpone the Fard Hajj until things improve in Saudi Arabia, thus allowing for a purer Hajj without involving haram?

Hajj for a woman whose husband doesn't have sufficient money to go for hajj

Q: My husband and I would have been accredited for Hajj this year but he asked SAHUC to remove our names before the list came out as he says he cannot afford it and Hajj is not Fardh on him. 

He does own 2 cars but does not have enough disposable cash to pay for the trip. 

Is Hajj fardh on him? I can afford to pay for my own Hajj
