What is customary is for us to say “Blessings and peace of Allah be upon him (sall Allahu ‘alayhi wa sallam)” specifically for our Prophet Muhammad (blessings and peace of Allah be upon him); is it permissible to offer this supplication with this wording for other Prophets? Who are the only ones for whom the following phrases are to be used: may Allah be pleased with him (radiya Allahu ‘anhu), may Allah have mercy on him (rahimahu Allah), may Allah keep him safe (sallamahu Allah)? Is it permissible to offer supplication for a great scholar who strove all his life to call people to Allah and His Messenger, such as Shaykh ‘Abd al-‘Azeez ibn Baaz and other, similar contemporary scholars, when they die, by saying “may Allah be pleased with him” or “peace be upon him”?

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?.

How should we call people to Islam?

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?

How can we prove to non-Muslims that Islam is a tolerant and easy religion?

If a man decides after a life of sinfulness to come to God and promise to reform his life, I understand that Islam says that he will be forgiven and therefore inherit the promises etc.
My question though is what has happened to the weight of this man's sin, as in sinning he has offended God and therefore this sin has to be atoned for; who is going to atone for his sin, if God is just going to forgive him on the promise of his being good and faithful? Surely as we saw with Adam there has to be a consequence for sin...

There are many religions.

Why do Muslims think that Islam is true. Is there any factual basis?

I have committed many sins which no one knows of except Allaah. What do I have to do so that Allaah will accept my repentance?

Who do Muslims worship?

One of the guys at work was asking me why I became Muslim and I told him it is the path I must follow. I don’t know sometimes what I should say, for me it is the path I must follow. What can I say to someone; I don’t want to push what I believe, so how should I answer someone if asked, what is the right way to answer the questions? Sometimes I feel I don’t give the right answers... Any clues as to what I can say?

According to the Quran and/or Islamic traditions, why did God create mankind?
