''The question was about CONVERSION by the sword.

Never happened.''

Hilarious, of course it happened, the reason why he raised an army was for the purpose of conversion.

''Muhammad was first and foremost a revolutionary, a fiery religious guerrilla leader who created and led the first genuine national insurgency in antiquity that is comprehensible in modern terms, a fact not lost on the jihadis of the present day, who often cite the Koran and Muhammad’s use of violence as justification for their own insurgencies. Unlike conventional generals, Muhammad did not seek the defeat of a foreign enemy or invader; rather, he sought to replace the existing Arabian social order with a new one based upon a radically different ideological worldview. To achieve his revolutionary goals Muhammad utilized all the means recognized by modern analysts as characteristic of a successful insurgency in today’s world.
Although Muhammad began his struggle for a new order with a small guerrilla cadre capable of undertaking only limited hit-and-run raids, by the time he was ready to attack Mecca a decade later that small guerrilla force had grown into a large conventional army with integrated cavalry and infantry units capable of conducting large-scale combat operations. It was the first truly national military force in Arab history, and it was this conventional military instrument that Muhammad’s successors used to forge a great empire.''
