Hajj & Umrah

Q: I was given to understand that Haji/Alhaj denotes a pilgrim in Arabic Language. After one has fulfilled his Haj and removed his Ihraam and returns to his native country he is no longer a Haji, i.e., a pilgrim. But, in my country India,  Hajis after their return from Haj Pilgrimage,
add a mandatory prefix title to their name i.e., Alhaj Umar for example, wherever they include their names whether it be wedding or other social invitations, letters, banners, media, etc. 

1. Is the usage of this prefix title of Alhaj allowed in Shariah even after a Haji returns from Haj?
2. Will it not be classified under Riy'aa ?(Showing Off)

Q: Is it haraam or in any way wrong to give gifts or arrange dinners for those who are coming and going for hajj? For example, if a friend of mine has returned from hajj, is it wrong (from an Islamic point of view) to give her a gift?

Q: My question is regarding dam (penalty) at hajj. On a few occasions during ihram I covered my head with a towel but took it off after I realize that this is against the rules of ihram but it was unintentionally. I asked a maulana about this and he said its ok. Also, during sleep I had my head covered with a towel for I don't know how long and when I woke up, I realized that it was on and took it off right away. Once again, this was unintentional, so I asked the maulana again and he said its ok but just give dam just in case.

Q: I performed hajj and I wanted to be safe and give dam (penalty) but I already left Saudia Arabia and now I'm at home.  Is it still permissible to give dam and who can I give it to?

Q: Is it true that a haajis duas are accepted for 40 days?

Q: I humbly request guidance on the matter of cutting hair in ihraam. What is the hanafi ruling on a person in the state of ihraam himself cutting the hair of his wife to come out of ihraam after completing the umrah? Is it allowed or is this a violation of ihraam? If it is a violation, will damm be due on the man?

Q: A person who is working in Saudi desires to perform Hajj. Can he enter the haram without ihraam, and before Hajj begins, he will tie his ihraam at the Aisha Miqaat and then enter with the intention of performing Hajj?

Q: Can my mother and my husbands father go for umrah with us?

Q: Can one wear a watch in the state of ihraam? Can one use the towel cloth that is being sold for purpose of Ihram?

Q: I am in Saudia. I want to perform Hajj this year. In Saudia one way of performing Hajj is to get a sort of permission letter (pass) from the Saudi govenment and the other way is to go directly and bypass the check post of Makkah to avoid checking of Hajj Pass. Mostly people in Saudia adopt the second way. I wanted to go by getting a Hajj pass but this year the Saudi government has issued very limited passes so I am not able to access that official pass. Is the second way off performing hajj permissible in Shari'ah or not? Because in that case we have to violate the Saudi law.
