Answer 1
Yes, Muslim leaders were tolerant of those they conquered because Muslim leaders were not seeking power or wealth or oppression. They were seeking only to free the will of the people to allow them to select freely their faith without any compulsion or aggression. Refer to questions below.
Answer 2
Muslim leaders have been different. you should specify. as an example when Muslims conquered Iran enforced Iranians to kill each other that is not an Islamic action.
Non-Muslim Answer
Muslims treated non-Muslims in a way that was superior to contemporaneous civilizations and introduced the concept of religious tolerance (as opposed to Europe which was practicing the exact opposite at the time). However, it is nothing close to the Muslim conception given above nor was it at all close to equality or Rights. An important thing to note is that the concept of Rights comes out the Enlightenment. Prior to this point, there was a system of privilege wherein the Ruler would provide privileges (out of the kindness of his heart) to a certain group of people to do acts. A person did not have the "right" to anything and this was the mentality worldwide.
The Muslim opinion touches on the Pact of Omar, which was a document of submission signed by the Caliph Omar and defeated Christians and Jews during one of Omar's Wars. While the factual accuracy of that story may be doubted, there is no doubt that the Pact of Omar formed the basis for the treatment of non-Muslims in the conquered territories. The Pact of Omar set out a number of regulations that will be described in this answer.
The Dhimmi, or non-Muslim under Muslim occupation was required by the Pact of Omar to pay a number of taxes that were connected with his Dhimmi status. The most famous was the jizya, which was a tax that Dhimmi had to pay for Muslims for the right to not be killed where they stood for not acknowledging Mohammed's Prophecy; it was a form of humiliation. Additional taxes included the kharaj, which was a tax on non-Muslim land-holdings in the Muslim World. The kharaj was so untenable that most Dhimmi were forced to live in the cities where the tax would not be applicable. The above answer is also incorrect as concerns justice. On paper, a Christian or Jew could testify against a Muslim, but in reality, such testimony was not acceptable and the attempt to defame a Muslim would receive retribution. Christians and Jews were not allowed to build new houses of worship, restore old houses of worship, proselytize in any way (this included religious debate or dialogue), or allow wine or pigs to be shown in public.
Polytheists were forced to convert to Islam with some rare exceptions (such as the Hindus in India). Zoroastrianism was the majority faith in Iran until Islam almost completely extinguished it, both by sword, economic inequality, and brutal repression of Zoroastrian customs (unless they could be Islamicized like Nourouz).
Sure. The proof on that is that Muslims controlled Spain for over 800 years and while the majority of the Spanish remained on their original religions over all this period. Muslims in Spain is less than 1% nowadays. Refer to question below.
