Islam IS the true religion of humanity.

[Mystical]

Can you give me examples for this conquered countries which was advanced in science , together their inventions and discoveries . I want to learn.

And can you explain me how you can make a person muslim by force ?

Well, to start off: the country of Spain alone, translates more learning material and literature into Spanish each year than the entire Arab world has translated into Arabic since the 9th century.

As the Saudi Grand Mufti bluntly put it in 2010, "The Quran with its stories and knowledge are sufficient for us... we don't need the Torah, or Gospels, or any other book"

First, the Muslim world benefited greatly from the Greek sciences, which were translated for them by dhimmi Christians and Jews.

Secondly, many of the scientific advances credited to Islam were actually “borrowed” from other cultures conquered by the Muslims. The algebraic concept of “zero”, for example, is erroneously attributed to Islam when, in fact, it was a Hindu discovery that was merely introduced to the West by Muslims.

Third, even accomplished Muslim scientists and cultural icons were often considered heretics in their day, sometimes with good reason. One of the greatest achievers to come out of the Muslim world was the Persian scientist and philosopher, al-Razi. His impressive works are often held up today as “proof” of Muslim accomplishment. But what the apologists often leave out is that al-Razi was denounced as a blasphemer, since he followed his own religious beliefs – which were in obvious contradiction to traditional Islam.

Fourth, even the contributions that are attributed to Islam (often inaccurately) are not terribly dramatic. There is the 'invention' of certain words, such as alchemy and elixir (and assassin, by the way), but not much else that survives in modern technology which is of practical significance. Neither is there any reason to believe that such discoveries would not have easily been made by the West following the cultural awakening triggered by the Reformation.

As an example, consider that Muslims claim credit for coffee - in the sense that they popularized existing knowledge of Africans who were caught up in the Arab slave trade.

In fact, the litany of “Muslim” achievement often takes the form of rhapsody, in which the true origins of these discoveries are omitted - along with their comparative significance to Western achievement. One often doesn't hear about the dismal fate of original accomplishments either. Those who brag about the great observatory of Taqi al-Din in [freshly conquered] Istanbul, for example, often neglect to mention that it was quickly destroyed by the caliphate.

At the end of the day, the record of scientific, medical and technological accomplishment is not something over which Muslim apologists want to get into a contest with the Christian world. Today’s Islamic innovators are primarily known for turning Western technology, such as cell phones and airplanes, into instruments of mass murder.

To sum up, although the Islamic religion is not entirely hostile to science, neither should it be confused as a facilitator. The great achievements that are said to have come out of the Islamic world were made either by non-Muslims who happened to be under Islamic rule, or by heretics who usually had little interest in Islam. Scientific discovery tapers off dramatically as Islam asserts dominance, until it eventually peters out altogether.

And can you explain me how you can make a person muslim by force ?

Is a child who is born, grown up told to believe in Allah or be killed, not forced?

Is a people who are subjugated by rules and regulations excessively until they convert, not forced?
