It has been the practice of Muslims to erect victory mosques in the lands of conquered enemies since the time of Mohammed. The Dome of the Rock and the Mosque of Cordoba are but two examples. And Islam is the only religion I know of with an express mandate to slay those who will not make a conversion. I provide translations of a few Quranic verses to provide illustration:
According to the Qur'an: "Muhammad is the Apostle of Allah. Those who follow him are merciful to one another, but ruthless to unbelievers" Surah 48:29. "Kill the Mushrikun (unbelievers) wherever you find them, and capture them and besiege them, and lie in wait for them in each and every ambush..." Surah 9:5. Also see Surah 9:29: PICKTHAL: "Fight against such of those who have been given the Scripture (Christians & Jews) as believe not in Allah nor the Last Day, and forbid not that which Allah hath forbidden by His messenger, and follow not the Religion of Truth, until they pay the tribute readily, being brought low.".
Surah 47:4 says:
Therefore, WHEN YOU MEET THE UNBELIEVERS, SMITE AT THEIR NECKS; At length, when ye have thoroughly subdued them, bind a bond firmly (on them): thereafter (is the time for) either generosity or ransom: Until the war lays down its burdens. Thus (are ye commanded): but if it had been Allah's Will, He could certainly have exacted retribution from them (Himself); but (He lets you fight) in order to test you, some with others. But those who are slain in the Way of Allah,- He will never let their deeds be lost.
Islam is, by its own profession, a militant religion that commands conversion by the sword as opposed to conversion by proselytization (sp?).
