1. What country, region or land in history has Islam conquered through peaceful means?
2. If Islamic leaders today are saying they will "conquer", "annihilate", and "kill every last one" of the Christians and Jews and take over their lands, do they mean what they say?
Mainstream Sharia books define Jihad as:
"to war against non-Muslims to establish the religion." (Shafi’i Sharia o9.0). Jihad is not just the duty of the individual Muslim, but it is also the main duty of the Muslim head of State (the Calipha):
"A Muslim calipha is entrusted to take his people into war and command offensive and aggressive Jihad. He must organize Jihad against any non-Muslim government, which prevents Muslim da’wah (meaning preaching and spreading Islam) from entering its land." (Shafii Law o25.0 to o25.9).
"(When the caliph appoints a ruler on a region, his duty includes) if the area has a border adjacent to enemy lands, (he will) undertake Jihad against enemies, dividing the spoils of battle among combatants and setting aside a fifth for deserving recipients." (Sharia law# o25.9)
"The Caliph makes war upon Jews, Christians and Zoroastrians until they become Muslim or else pay the non-Muslim poll tax provided he has first invited them to enter Islam or pay Jizya, the non-Muslim poll tax, (in accordance with the word of Allah Most High Chapter 9 verse 29)."
"Jihad in terms of warfare is a collective responsibility of the Muslim Ummah." (Zia-Ul-Haq, former President of Pakistan)
"Islam wishes to destroy all states and governments anywhere on the face of the earth which are opposed to the ideology and program of Islam regardless of the country or the nation which rules it. The purpose of Islam is to set up a state on the basis of its own ideology and program … the objective of Islamic jihad is to eliminate the rule of an un-Islamic system and establish instead an Islamic system of state rule. Islam does not intend to confine this revolution to a single state or a few countries; the aim of Islam is to bring about a universal revolution." (Sheikh Maolana Maududi 20th Century Islamic Scholar)
