Toma_tto;
I read your post and I have few answers and questions for you:
I am a borned Muslim in Singapore and i have been confronted by my friend on my belief in my religion " Islam ". and i have search the web for answers and today , i really question myself, is my belief right? I am seeking my fellows brothers and sisters to read below and feel your heart and answer me honestly and genuinely
Being a Muslim does not mean having a Muslim parents only.
You have a duty to learn about Islam and understand what it calls for.
When that is done you will have no doubts about it.
I agree with curioustraveler, you do not learn Islam from internet but from a knowledgeable Muslim. I hope you will do that, then you will have all your questions answered.
1. Why is the book , koran full of violence ? Yes, it only teaches us to retaliate , but why do we have to resort to violent? can we persuade them, talk peacefully?
You do not understand Islam so how can you understand Quran? from the internet too?
Islam does not call for violence. Does the Bible call for Violence. They both call for the spread of the religion, and fighting the people who wants to destroy it, and its people.
Do you know that in Quran it calls for peace, forgiveness, kindness....too?
2. why do i believe in a prophet who has so many wives and have sex with a 9 yo girls? this is really unacceptable , did Jesus or Buddha have a promiscuous life style??
The one who created us knows what is best for us. Prophet Muhammad (peace be upon him) is the best of Allah's creation. We believe in him because that is the order of Allah. To be a Muslim is to obey Allah's orders.
He did not marry because he loved women, he married his first wife who was 40 years old when he was in his twenties (25). He remained with her, and only her until she died at the age of 65.. So he was 50, and he stayed without a woman for the next two years, raising his girls alone. Does this sound like a man who wanted younger girls?! Definitely not.
And his next wife was 80 years old..
All his wives (May god blessed them all) except for " Aisha" were married some once and some more before he married them. The girls at that environment and time were maturing much earlier than now, and marrying her was acceptable by the society, and her, her parents. If there is something you do not like or understand, does not make it wrong.
Qurayish offered prophet Muhammad (peace be upon him) the most beautiful girls of his tripe and to make him the richest and he refused with no hesitation. What do you say about that?
Each marriage had a reason and had a purpose, and none were for what you think.. and that is why he is the best of God's creation.He (peace be upon him).is not like any man
4. Why are terrorists muslim?? there must be something wrong with our koran!!
5. Why can't we live in peace with any other human on earth??
Are you telling me that the people who got killed in Vietnam were killed by Muslims! and the people in Uganda, Nigeria, Rwanda..Ireland, Nepal..
Was Hitlar a Muslim?

!
Muslims live all over the world in peace with other people form different background and religion.
Do you know how many Muslims in the world?
Can you tell me, what percentage of them terrorist?
Open your eyes, and do not look at "Islam" through a distorted lenses. Learn about it before accusing Islam and Muslims.
