2. Is it true that if I will go to Arabic / Islamic country I could be killed ? Just because I am christian, my cross on my chest , christian name , etc.

This I don't know. But perhaps other members familiar with the Arab-Christian situations will know. As far as I know from sitting here in North America, it is both safe and unsafe. People tend to become violent when there is severe destabilization in their countries. So if any Arab-Muslims kill Christians, it will stem from those who scapegoat Christians in order to act like they are finding a solution. Thus, if it happens, it is less about religion and more about false solutions to a very different problem.

4. What if someday We will finally realize that we are not alone in the universe , how Quran describe that ?

Allah says He will gather them someday together. So yes, the Qur'an says that there is extra-terrestrial life:

42:29 And among His Signs is the creation of the heavens and the earth, and the living creatures that He has scattered through them: and He has power to gather them together when He wills.

Whether these are intelligent beings like us or merely bacteria, no one knows. But Allah has created a vast universe, and He is "Lord of all the Worlds" (1:2), thus, He has many worlds on which He is potentially worshiped.

5. Why muslim woman cannot show a face to public ? If I'm not wrong it's Hijab , right ?

Because women in Islam are considered of distinction. Think of it this way, even female princesses and high-level female authorities in general, in many different nations of the world, would keep themselves covered from the eyes of others by being transferred in hidden carriages, either held by other people, ran by horses or otherwise. This has been a common form of distinction of class. Muslim women are all considered to be of a distinct class of women, who are close to God, and therefore much more noble than other women who are not Muslim. Instead of this division being due to money, it is due to one's close proximity with the Lord of the Universe. The Lord of the Universe is the King of kings, the God of mankind, the King of mankind, thus, He is more worthy to be covered for than any other king of this lowly world.

6. I am kind of science person , what do you think about this- what if we all talks about the same GOD but told in different stories ? Why we have to fight about which religion is most authentic ? Maybe it is all about the same but told in different values , it was very long time ago right , it's like someone at school tell a rumor to everyone but fianlly this is not a true.

I love science as well. However, the true point to note is that the God of this universe did not reveal any Word of His to mankind that is in contradiction to what we see. Perhaps in some respects, our conclusions about what we see in this universe are wrong, but the Word of God is not in contradiction to the correct conclusions which we arrive at about nature. Allah created everything, thus He knows His creation better than we do.

As for God Himself, every religion revealed before Islam was sent to different nations. Think about how different every nation and culture is for a moment, and then think about how laws would have to be drastically different in order to accommodate that. This is why spiritual laws, the laws which God gave to every nation, were different. The religion of Islam was given to everyone before, Islam is not a new occurrence. Islam simply means 'submission', it is a continued religion since Adam (as). Every Prophet of God, all 124 000 of them, came with revelations from God. This is not from just 6000 years ago, but from tens of thousands of years into the past.

Thus, the religion revealed to Prophet Muhammad (peace and blessings of Allah be upon him), was the final law, which was given to all of mankind. No Prophet before him was sent to the whole world, and no Prophet of God came with a final law for mankind. This is why he is the "Seal of the Prophets". It is also why we Muslims are bent upon spreading Islam to the whole world, because unlike Christianity, our religion has been designed for the whole world, because Allah was the "God of mankind" in the Qur'an, not "The Lord God of Israel" only. I say that respectfully, since I have read the Bible before, and found this careful distinction. Thus, no religion should be fighting one another. The Holy Qur'an says:

3:64 Say: "O People of the Book! come to common terms as between us and you: That we worship none but Allah; that we associate no partners with him; that we erect not, from among ourselves, Lords and patrons other than Allah." If then they turn back, say ye: "Bear witness that we (at least) are Muslims (bowing to Allah's Will). 3:65 Ye People of the Book! Why dispute ye about Abraham, when the Law and the Gospel Were not revealed Till after him? Have ye no understanding?

Therefore, Allah has said clearly in the Qur'an, that there is no need for any controversy regarding the belief in Him. If we all hold that common belief, that alone should unite us all together.

7. Why muslim man is so agressive when someone is going to touch his wife , even accidently ?

This is probably a cultural phenomenon. I have spoken with many non-Muslims who have this same issue. I believe this is a human trait, and this is why the Holy Qur'an tells Muslims to "not even go near adultery" (17:32) and for men and women to lower their gazes (24:30-31). This is to protect each other's chastity, and to remove any ill-will that could creep into our behaviors with one another. Most men are aggressive in this sense. I would be, shouldn't you as well? I can't count how many rape cases there are with women in the world. This is because men don't control themselves and their sexual urges. Islam is about controlling these urges, and limiting ourselves to our wives. Even looking at women the wrong way is not for men to punish, but Allah is making us aware that He punishes this. So those men who get aggressive shouldn't do so, since Islam is about forgiveness and leniency.

Those men should inform others not to touch their wives, and they should control their anger. This is because anger is from Satan, and there are methods prescribed in Islam to deal with anger. If one controls their anger, Allah is well-pleased with their actions.

8. Why Islam let adult person to have a sex or temprary marriage with girl in age 12,13,14,15 + ?

Temporary marriage was a short-term occurrence in Islam, and the Holy Prophet (saw) forbid this to the Muslims after one of his battles with the disbelievers. I can't remember which one. But Islam does not let adults have sex with prepubescent girls. Puberty is the stage at which a Muslim becomes an adult, regardless of the age in which they attain it. Thus, girls' puberty can start from as early as 8 years old - and this is according to medical studies. If you look up the age of puberty, you will find there is no fixed age for it. However, the official age of adulthood for both men and women in Islam is at 15 years of age. The basis for this was when one Companion of Prophet Muhammad (peace and blessings of Allah be upon him (SAW)) wanted to fight in a battle one year, he was rejected - at that time he as fourteen. The next year, when he was fifteen he enlisted again, and he was accepted because he was considered an adult. So besides the signs of puberty, such as menstruation for women beginning and boys getting pubic hair, the age of 15 is the age of adulthood in Islam. Thus, whatever the case, Islam does not allow marriage, and therefore sex, with prepubescent girls. Only adults are allowed to get married. Albeit, adulthood is defined differently, which has been the prime cause of misunderstanding for Christians on the Islamic perspective of marriage even until now.

9. I am a person who love animals, why in Islam there is ritual who permit to kill animal without any dope ? In my country this is strictly watched by association of animal protection.

Islam has a long list of animal rights laws mentioned by Prophet Muhammad (SAW). The only cases in which killing is allowed, is for rabid dogs, black dogs (which were considered dangerous), rats, venomous snakes, etc. Any animal that was harmful to a human being was liable to be killed.

In terms of hunting, Islam only allows hunting of animals which are killed for food. Hunting animals for fun is strictly forbidden, because that is considered a form of animal cruelty. Thus, hunting birds for the sake of their game is not allowed, nor for any other animal. Tying up an animal and killing it while it is incapacitated is also strictly forbidden. Denying an animal food is strictly forbidden, and it is forbidden to kill an animal by a violent blow and then eat it. Only animals slaughtered by reciting the Bismillah, cutting at the throat with a well-sharpened knife is allowed. In fact, as Muslims, we have to consider the feelings of an animal so much that we have to keep the knife hidden from its view. Otherwise, the animal might become afraid of getting killed when it sees the weapon. So not only do we respect the animals as creatures, but we respect them as intelligent beings.

There is a famous story which is in the Traditions said by Prophet Muhammad (SAW). He said that there was a prostitute once who had most likely slept with many men. She was considered very sinful by Allah. One day, she passed by a dog during a hot day, and the dog was panting from the extreme heat. So this lady took her shoes off, and went down into a well and fetched some water for the dog. She used her shoes to get water for it and gave it to it. The dog's thirst was quenched after she did this enough times. Jut imagine, she used her shoes to feed this dog. And because of this, the lady was forgiven all of her previous sins by Allah. And this is a woman who was a prostitute, who had committed a major sins multiple times!

Another story shows the opposite effect. One time this lady had a cat. It bothered her often. So out of being annoyed by the cat, she locked it up and kept it from eating until it died. Due to her cruelty, and not allowing the cat to eat even from the vermin of the earth, she was condemned to Hell by Allah. Thus, you can see the displeasure of Allah by cruelty to animals, and the pleasure of Allah at kindness towards animals. These are two very popular instances about animals from the Traditions.

10. Does the muslim world supports terrorist groups ? Are you shame because of extrimists ? What is your opinion about that ? Does the Quran describes somehow this what terrorists do ?

They are certainly shameful. The reason why they are in the wrong, besides everything else they do, is that they are extreme in Islam. Islam is not a religion about going to extremes, because Prophet Muhammad (SAW) did his absolute best to keep the earliest Muslims away from extremism. These terrorists are, by the very definition of the term, acting against Islam. The Holy Qur'an says:

5:32 On that account: We ordained for the Children of Israel that if any one slew a person - unless it be for murder or for spreading mischief in the land - it would be as if he slew the whole people: and if any one saved a life, it would be as if he saved the life of the whole people. Then although there came to them Our messengers with clear signs, yet, even after that, many of them continued to commit excesses in the land. 5:33 The punishment of those who wage war against Allah and His Messenger, and strive with might and main for mischief through the land is: execution, or crucifixion, or the cutting off of hands and feet from opposite sides, or exile from the land: that is their disgrace in this world, and a heavy punishment is theirs in the Hereafter; 5:34 Except for those who repent before they fall into your power: in that case, know that Allah is Oft-forgiving, Most Merciful.

Thus, these extremists are killing people left and right, while the unlawful killing of just one person is like killing all of mankind. This is the sin of murder. On top of that, they are killing Muslims as well intentionally, trying to establish Shari'a in Islamic governments. What they are doing is foolish because killing a Muslim lands a person into Hell:

4:93 If a man kills a believer intentionally, his recompense is Hell, to abide therein (For ever): And the wrath and the curse of Allah are upon him, and a dreadful penalty is prepared for him.

And yet, they do this very often. The Qur'an is full of arguments against terrorists. But these verses are clearly showing that their killing without any valid reason, for the mere purpose of spreading mischief (i.e., terror) is very much hated by Allah. They don't fight for Islam, they fight for their own political whims. Islam is not about harshness, nor forcing people to believe:

2:256 Let there be no compulsion in religion: Truth stands out clear from Error: whoever rejects evil and believes in Allah hath grasped the most trustworthy hand-hold, that never breaks. And Allah heareth and knoweth all things.

There is no compulsion in Islam. So these terrorists are in the wrong with spreading Islam violently and forcefully. Their actions are all against the Qur'an, and they have no concept of this beautiful religion.

If I hurt you somehow with this questions I am sorry , I don't know what I am allowed to say when I talk to muslim.

Don't be so worried. Ask all the questions you need to. The moderators of this forum do a great job in moderating the conversations.
