A non-Muslim friend of mine asked how I could prove the existence of God and why He has given us life, and what its purpose is?
My answer did not satisfy him, please tell me what I should tell him?

In my school it is Christmas time. My school has this Christmas tradition. Every year a classroom gets an adopted family that is poor so they can buy gifts, food, and donate money to them for Christmas. Unfortunately, I have refused to donate any money or give any food for the following reason: These denotations will be done in the name of Christmas, so that when the adopted family receives these donations, they will say "God Bless The Christians". 
Am I right for refusing to give donations?

I am looking for an easy way to memorize the Holy Qur’aan.

I don't celebrate Christmas in any way, but my 11 year old daughter loves the beauty of a Christmas tree when decorated. Is it permissible for me to have one in my house throughout the year?

A man is experiencing waswas (insinuating whispers) from the Shaytan (devil) having to do with Allah, and he is very afraid of that.

Will a person (a believer) be rewarded if he listens to the Qur’aan without understanding what he is listening to, but he knows that it is Qur’aan? Or will he not be rewarded unless he understands what he is hearing? I hope you could give some evidence from the Qur’aan and saheeh hadeeth.

Can you give us an idea about the Dajjaal, Al-Daabbah and Ya’jooj and Ma’jooj?

In Sahih Bukhari, it is mentioned that ...70,000 of all mankind will enter paradise(!!!)
The first three generations of muslims alone probably amounts to 70,000.
Is there another explanation to this hadith?

Is it mustahabb to say Qunoot during the daily prayers for our brothers in Gaza, so that Allaah will relieve them of the aggression of the Jews? In which prayer should Qunoot be said?

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

Assalaam O Aliekum. Fajr Salat at the mosques in my locality start 30 mins before sunrise, and redishness in the furthermost eastern horizon is clearly visible. Is this indicative of the expiry of the time for Fajr? Would I be better off, offering Salat a little earlier without congregation at home?
