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

A brother of ours has recently become Muslim. During his days of Jaahiliyyah (ignorance – i.e., before he became Muslim), he earned a lot of money by dealing in drugs. He brought this money with him and opened a big bookstore and got married using this money. Recently he has been told that it is not permissible for him to give this money in charity, because Allaah is Good and only accepts that which is good, Our question is, what should he do with this money, and how sound is what he has been told?.

My question deals with a friend of mine who was ignorantly joking. When my friend was teased by another friend he ignorantly picked up his phone out of joking and said I have to tell Allah. Then he said on the phone "Hello, Allah" as to tell Allah. I know this is incorrect but is this shirk?

This is quite an embarrassing question which I am finding difficult to ask anyone. Please could you tell me exactly which parts are you supposed to wash when doing istinjaa? Is it sufficient to just wash the orifices or should one wash the whole penis and the areas where one has pubic hair in this region?

I have heard that there is a certain attitude that the Muslim should adopt if he faces a time of fitnah (tribulation). What is the attitude towards fitnah?.
