What are the Virtues of the Day of Arafaah?

Is it true that anyone who does not accept that kuffaar are kuffaar is a kaafir himself, even if he prays, believes in the Qur'aan, and the Prophet Muhammad? If so, what is the proof for this? Can a person insist on believing that Jews and Christians can be believers and go to heaven after being shown clear evidence against this, and still be considered a Muslim?

What is the difference in meaning between Allah's names al-Rahman and al-Rahim?
 

I have a few questions concerning parents:
1. What right does my Mother have over me? 
2. What right do I have over my mother? 
3. What do I have the freedom to do (which is Halal or Mubah, Ofcourse) without my Mother having the right to stop me? 
4. When does the Father have the final say in a matter? 

I love my mother very very very much. She is very over protective, and sometimes I feel like I'm in chains. I know she is doing it out of extreme love for me. How can I tell her that I need a little choice of my own in life.

Is it valid to read Qur’aan from the computer instead of from the Mushaf ?
In other words, reading from websites on the Internet or from text files that contain the entire Qur’aan, which is displayed on the computer screen. I work in a company and during my breaks I read Qur’aan on the computer.
Is it necessary to have wudoo’ for this kind of reading, as is the case when reading from the Mushaf?.

1. I would like to know the dividing line between hypocrisy and courtesy, because in many cases I feel that there is some two-facedness in people's behaviour and dealings, based on their interests and whims and desires, and it is said that it is just courtesy. Is this true? 

2. Is it possible for true friendship to be mixed with a little hypocrisy? I have a friend who does not love me as I thought she did. She held a special place in my heart that was shared by no one else, but recently I found out that my status with her is zero, and her behaviour with me for many years was superficial. I thought, and everyone was certain about that, that our friendship was strong, and until now I do not know how to end this friendship after finding out what is really going on. 

3. Can the way this friend behaved be regarded as hypocrisy? 

4. What is the punishment for hypocrisy in friendship?

When I went to do ‘umrah, I was menstruating, so I did sa‘i and cut my hair, and I exited ihram and put on niqab. I waited until I became pure, then I did tawaaf at the Ka‘bah. I did this based on the ruling on Hajj, which says that the menstruating woman should do everything except tawaaf. Please note that I am not married. What is your opinion, may Allah bless you?

There is a Quran out which is called "Quran pen reader 9" which helps you better your tajweed and you can listen to different reciters and when you press the Quran with the pen they give it says it out loud the verse you have pressed and you can pick different reciters so you can remember it and correct your tajweed and the Quran it self has interactive buttons on the side like e.g tafsir of the ayah ,which qari you want to chose ,change the level of volume and pick which language you want etc
I wanted to know do I still read this Quran like a normal Quran and will I get the same reward of reading this then a normal one were this one helps me correct my mistakes and makes me understand the Quran more and it is the full Quran with just it being interactive and I was thinking will this be a sort of bidah? But theres more benefit in this as I have mensioned everything this does for the improvement of understand and correct my tajweed and knowledge in the Quran ?

I want to know about ‘Umrah in detail.

Is it permissible to read Qur'aan while a women is having mensus (periods)?

I have very difficult question and I think this is my only hope that you can help me to find the answer.
I am a Russian Jewish girl and I know this Muslim guy for over a year. The longer we know each other, the more problems and difficulties we face. Not in the religious or cultural ways. We love each other and there is an issue of whether he can marry me or not.
He is a very good Muslim and he comes from traditional family. I am very fond of his beliefs and beliefs of his family. I was born in a very agnostic country and couldn't be properly introduced into any religion. It was forbidden. When I came to the US I started my research on different religions and found out that my beliefs do not really match all Jewish sayings. I did a lot of research on Islam and by looking at him and a couple other Muslim boys and girls, and by reading Quaran, I have a very strong feeling that I could become a good Muslim. I want to go to school to learn the culture and religion more precisely, to learn the language. I contacted the mosque and was ready to go... but I faced the issue: would I be accepted as a Muslim sister like other people who came from different religions except Jewish? Jews and Muslims are in big contradictions and I know that friendship is almost impossible. I am praying to God (in my home language - Russian), to lead me the right way to achieve my beliefs.
Please, help me to find my answers
