How should we call people to Islam?

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?

I am one of those who send blessings upon the Prophet between 50 and 100 times a day, according to circumstances. I say: “Allahumma salli ‘ala Muhammadin wa aali Muhammad (O Allah, send blessings upon Muhammad and the family of Muhammad).” There are some people who tell me that my sending blessings upon the Messenger of Allah is lacking. Can you tell us – may Allah reward you with good – what is the ideal way to send blessings upon the master of mankind, and is the way I am doing it really lacking?

I understand that hijab is required, and I’ve been wearing it for some time now but I feel like putting it on might have been a mistake.  I don’t feel like it’s made me become a better Muslim, and I feel almost like I’m deceiving people because they look at me as an example even though I’m still struggling with a lot of things. Also, if I take it off, is it really something Allah will punish me for? It seems like such a petty thing. Isn’t the most important thing having a clean heart?

We celebrate the birthday of Prophet Muhammad (peace be upon him). On this day, we read a lot of salutations on him and engage in a lot of prayers to Allah. We try to show our love for our Prophet (peace be upon him). How come you say we cannot do it?

Is divorce issued by a civil court valid?

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

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?.
