Those people upon whom Hajj is compulsory

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?

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

Q: If a person had a struggle to get a job, he got a job and then saved up and he had enough money to get a basic Hajj package but if he doesn’t have time off that he can request from work, would he leave his job and do Hajj or would he keep his job and intend Hajj the following year?

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

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: If my wife is pregnant and is due to give birth during the time when I will be away for my fardh hajj, can I still go for hajj and leave her alone or should I delay my hajj?

Q: If a person has haraam wealth due to usurping the rights of people, or haraam wealth earned through ribaa (interest) from the banks or from any other source, can he use this wealth to go for hajj? If he goes to perform his fardh hajj with such wealth, will his hajj be valid?
