In the Name of Allah, the Most Merciful, the Most Gracious

Well it's not my disability of answering your question(s) that made me late, it is the time that I need to find a translator to translate my answers. So I'm asking everyone to forgive me for being late. O.K. I'll answer some of the questions:
1) when some Muslims blew up buildings and the story of having pilots for practicing that was a mistake; and I didn’t mean mistake as something happens without purpose. No, I didn’t mean that. What I meant was that those who were involved in bombing operations made a huge mistake. For that, I and the Muslims in the whole world are innocents of such operations. Those people made a huge mistake in such operations and horrible bombings but that doesn’t mean all Muslims are in such a way of behaving, that's what I mean. Maybe I didn’t translate each "mistake" word a correct translation; I mean the mistake of doing something horrible and guilty and so on. And I didn’t mean a mistake that is something wrong happened spontaneously.

2) as for the Islamic world that had nothing to do about that as you presume????
Well if you remember that most of the Islamic countries' presidents had bad comments and withdraw themselves of such terrifying operation, this is ONE.
TWO is when some Muslims blew up the two buildings (towers), the United States after a short time had punished some of those who had been involved in that. So they entered to Afghanistan and arrested some and many of members of the organizations which had some relations in that. The matter was that some Muslims had committed a big mistake ; bombing the two buildings. So as any country in the world, the United States won't keep silent of their rights and the souls of their people, either. So they punished the involved ones in Afghanistan and had built there prisons for them to take back their honor, so what can we do after all??
Dear brother, America has punished and arrested the terrorists in Afghanistan as soon as they got in there after the explosion and arrested some of them, and we as Muslims and especially Islam has denied that and it's out of guilt of such operations and bombings. Again as I told you America is the one who arrested them there, and that doesn’t mean that we didn’t arrest them then it is good for us, no!!!!
Take a look of this example: when some Muslims had killed a French man in a Muslim town, what did the Muslim government do???? they didn’t waste much time; they searched each spot of the country till they arrested them. So either they killed them for killing the French or put them in prison forever underground, and we as Muslims do not accept such a thing , even Islam ordered each Muslim to treat anyone who isn’t Muslim with good manner and politeness, so how is it with those who live with us????!!!!
And as for your saying that we didn’t arrest the terrorists???
Well America has arrested them directly in Afghanistan because it was the shelter of those who had involved in the bombing and they weren’t in our country , so the United States arrested them and had revenge on them.

3) Why the Sunna and the Shei'ah do not go along with each other???
Well this incident has a background story and history. Many things happened that time. What I can say is that the Sunna are Muslims who have been performing the rules, morals and habits which the Holy Qura'an and prophet Muhammad peace be upon him called for since the prophecy of prophet Muhammad peace be upon him till now. In a word, they are the true Muslims who quite follows the commands of the Holy Qura'an and the prophet peace be upon him. That means Islam doesn’t know Shei'ah or any group. It hasn’t take it officially either. Muslims have the instinct of following their religion and holding whatever the Holy Qur'an and prophet Muhammad have asked through his says and deeds. they are called Sunna because we call the speeches of the prophet as sunna. If you see and live with the Sunna group, you will see the true morals and commands of Islam. Those are the true Muslim group. Whereas the Shei'ah, which Islam never knows or even even accepts, had shown after many Islamic historic events. Some of them are Muslims who testified that there is only one God and Muhammad is his messenger, while others Islam has never accepts them and are not really Muslims. They happened to come because of some revolting actions. They had a private Imam, strange and different kinds of faith, and origins of religion; which means they made Islam up side down. Some of their faith had turned from Islam. They do things Islam has never asked. Some of them believe that prophecy was never for our Messenger Muhammad. So some of them aren’t Muslims and turned from Islam. The difference between them and us; the Sunna, is that the sunna follows the Holy Qur'an and the speeches of prophet Muhammad (peace be upon him) while the Shei'ah follows its own Imam, rules and desire. The Shei'ah hates the Sunna because the latter declines the wrong faith of the former. They think they are the Muslims, the best and the correct ones. However, they know that the Sunna are the ones who follows the principles of Islam. The Shei'ah says: "Why the Sunna revolt us while we are the best Muslims." Because of the huge difference between us and the faiths of the Shei'ah. You see that the Shei'ah hates the Sunna because they believe that they must hurt the Muslims of sunna. They had shown up because of tales and incidents including ideas doesn’t belong to Islam. They, again, hate suna because it denies their faith , and if you have the chance to see them, your'e going to see something weird and have a bad point of view, while some of them aren’t truly Muslims.
