Muslims treat all non-Muslims; irrelevant to their faiths; with tolerance, forgiveness, and mutual respect. This stems from the Islam teachings per Muslims holy book Quran and per prophet Muhammad (peace be upon him) teachings. Muslims treat Christians and Jews and all non Muslims kindly and with tolerance so far they don't attack Muslims, they don't expel them from their lands and homes, and/or they don't fight them. Quran; Muslims holy book, and prophet Muhammad (PBUH) call for kind treatment and with tolerance with all non-Muslims. Muslims follow the Islam teachings that no compulsion in religion. They conquered land but never conquered people. It was their aim to free the will people and not to exploit them or exploit their resources. Refer to the example of Spain. Muslims transferred to Spain all kinds of development and technologies. Refer to questions below.
Europeans traveled to the Middle East to conquer the lands under Muslim control because of that was the supposed Holy Land, were Jesus was born, they were armies of religious fanatics who dropped everything to go fight for God. This caused amazing amounts of destruction and I would not be surprised if all the troubles in the Middle East today stem form this initial string of conflict and Holy Wars, as for the question it is one that needs to be answered in a library with lots of hours of research on the subject, including studying all the various battles that allowed for the Crusaders to enter so far into the Holy Land. I recommend you search Crusades or Holy Wars in wiki to get you started.

Comments on answer aboveThe first incursion into India by the Muslims occurred around 664 CE during the Umayyad Caliphate, led by Al Muhallab ibn Abi Suffrah towards Multan in Southern Punjab, in what is now Pakistan. The aim was not conquest, and he returned with wealth and prisoners of war.

Answer: When Muslims are true to their faith, they can conquer anyone. God says, in the Qur'an, that anyone who worships other than the One God is weak. They do not have the help of God and, so, will be conquered easily. The reason Muslims are themselves conquered today is simply because they are not true Muslims. They are weak and hyppocritical - or they are extremists who kill innocent people. So they do not have the help of God. www.freequran.org
