Tying one's ihraam in the plane

Q: I will be leaving for Umrah in a week. I will be landing in Jeddah, and I will have to be in the state of Ihram. I have a few questions regarding going into Ihraam. 

1. I will make the ghusul in South Africa that morning before I leave for Jeddah. Will it be valid if I go into Ihraam on the plane before landing in Jeddah?

If I go in to Ihraam on the plane must I make the the 2 rakaats of Sunnat Salaah on the plane.

2. As mentioned in question 1, if I go into Ihraam on the plane, must I proceed straight to perform Umrah or I may go to the Hotel?

3. As mentioned question 2, if I can go to the hotel and then perform Umrah, can I remove the Ihraam I was in and make ghusal and re-enter in to Ihraam?

Talaaq-e-baain and irrevocable talaaq

Q: Me and my husband has had many arguments for the past 2 years. And everytime he keeps saying "Tum meri taraf se farigh ho" - "Tum meri taraf se poori farigh ho" and at the same time he also keep saying "I dont want anything to do with you. Leave this house and do what ever you want to do and go where ever you want to." Sometimes he says sorry and sometimes we dont talk for weeks.

1. Does that mean that he divorced me completely? Am I still in his Nikah or not?

We had arguments again today where he said "Tum meri taraf se farigh ho" and I said if you dont want to keep me then tell me clearly that you are divorcing me. But then he tells me to write down myself that I want a divorce from him. Even though its him who keeps saying it. I never wrote it down on a paper. I dont want to get divorced.

2. What does Talaaq e bain mean? Im a bit confused about what it is.

3. And what is "Revocable Talaaq"? And "Irrevocable Talaaq"? And what is the difference between them?

Will a person who has two houses in different countries perform full salaah or qasar salaah?

Q: I lived in South africa for many years, then for some reason I moved to another country with my whole family. However, I still have my house in South Africa and I have the intention to come back and live in this house after a few years.

My question is that if I come to my house in South Africa for 3 days just to see if everything is alright, will I be a musaafir or not?

Wife masturbating her husband

Q: Is it allowed to make your husband ejaculate by rubbing his private parts? I usually hold the private part in my hand and husband then holds my hand and rub the private part means my hand is between his private part and his hand. His hand is not directly touching his private part. So will it be allowed to make him orgasm in this way?

Book on heaven and hell

Q: May I have a detailed account of the following from Quran and Ahadith (all ahadith and ayaat which say anything regarding them):

1. The horrors of Hell

2. The pleasures in Heaven.

If there is a book regarding these, may I also know the names?

Imaam saying "samiallahu liman hamidah" instead of "Allah akbar" in salaah

Q:

1. In our college, the student imam, in between 2 sajdas forgetfully said, "SamiAllah huliman Hamida" instead of "Allahu Akbar", he did a 2-3 second pause and went for the second remaining sajda. The people behind him didn't even correct him but the second row guys had to correct him, by saying "Subhan Allah". After the completion of Salah, there was a big argument,

a. 3-4 people did sajda sahu after salah

b. The rest of the guys said "the Salah has to be repeated because the imam's niyyat is muqtadi's niyyat and if he makes mistake, it affects everybodys salah"

After that, the whole Salah was repeated by a different imaan. Who was right? a or b?

2. The imaam got up from ruku, and said "Allahu Akbar" instead of "SamiAllah huliman Hamida". The people behind him didn't correct him. The second row guys corrected him the wrong way, but this time by saying "SamiAllah huliman Hamida" instead of "Subhan Allah" and at the end, the imaam didn't even make sajda sahu. I have to repeat the Salah right? Because I have heard the imaam's niyyat is the muqtadi's niyyat and if he makes a mistake, it affects everybodys salah.

Going to work early

Q: I am working at an engineering company. My boss used to like me before because I was always at work early. We start work at 7:30am but I used to be at work before seven and I used to get extra money, but now I am going to work at the normal time 7:30 because I read Suratul Yaseen and azkar... My boss is not happy with me like how he was before. What should I do? Should I go early and miss my Suratul Yaseen or should read Suratul YAseen before I go to work?

Advertising for businesses and companies

Q: I want to put up some advertising boards in my town and get shops and companies to advetise on and charge them. Is this permissible?

Secondly, I wont get companies that are dealing in haraam to advertise with them, so it will probably be businesses like supermarkets and hardware stores etc. But my problem is that am I allowed to advertise for them if a part of their business might be haraam or doubtful. For example I personally dont eat commercial chickens even though it might have a halaal stamp on it. I prefer to stay away since I feel it is still doubtful, will I be able to still advertise for that supermarket that sells it. Or if there is a car dealer who sells cars but organises a loan for a customer based on interest then am I allowed to advertise for him.

Also is there any guidelines that you can give me and advise?
