What are the signs of Allah's love for His slave?

I have read the many pages of your web site that instructs a non-believer. I believe that there is only Allah (one God). Ibelieve that Muhammed is the seal of the prophets. History bears this out. My question is: How do I declare this (shahadah) if I do not speak arabic?  How do I perform the five daily prayers (salah) without understanding arabic? Finally would I have to change my name?

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...

Who do Muslims worship?

Is it permissible to eat food that is distributed on the birthday of the Prophet Muhammad (peace and blessings of Allaah be upon him)? Some people quote as evidence the idea that because Abu Lahb set free a slave woman on the birthday of the Prophet (peace and blessings of Allaah be upon him), Allaah reduced the torment for him on that day.

Is it permissible to pray in a mosque where the ground floor is controlled by the Shi‘ah and the Sunnis control the upper floor?

I hope you can give me some examples of good deeds that we can do every day to increase our hasanaat.

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?

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 true that the person who is used to studying in Islamic schools, and has no previous experience of studying in non-Islamic schools, will never be able to connect with the environment that surrounds him, where most of the people are non-Muslims and that he will grow up shy and will never find any way to succeed either in his academic life or in the workplace? What is your opinion about that?
