Haaji being turned back at the airport

Q: I want to ask you a very important question regarding Hajj as we are unable to find the answer to this problem. My parents were supposed to perform a Hajj this year, everything was set, they received their hajj visas, had their tickets booked too, but the day of their flight, a letter was issued by the government of Saudi Arabia that no more hajis are allowed to perform hajj after 5 Zil Hajjah. Hence, my parents returned home as the staff at the airport wouldn't let them go. My parents did the niyyah for hajj but hadn't worn their ihraam yet and decided to wear it upon reaching Dubai so that they could wear it from Dubai to Saudi Arabia. The question is whether they're supposed to pay kuffarah as a verse related to this is mentioned in Surah Baqarah. My parents are confused regarding this and seek guidance. Kindly guide us through this problem whether they should pay kuffarah and if so, what should the kuffarah be.

Haraam relationship

Q: I'm in a relationship since the last 3 years. I know it is haram and I want to end it but whenever I try to end it he blackmails me by saying he will tell it to my family and will show my conversation to my parents and siblings. I'm afraid of the disgrace my parents and brother would suffer because of me. I somewhere inside also want to marry him but in a halaal way. Please guide me.

Becoming despondent

Q: I feel very disturbed right now. I know I havn't been sincere the whole time I was practicing deen and I have even had polluted intentions of practicing whole deen. From what I understand is that none of my ibaadat will get excepted except durroods. What can a person like me do in this situation. I know that I still need to obey Allah regardless but I feel very miserable right now and it is affecting my ibaadat. Please help.
