There was never a time, beginning with the sand-pirate turned prophet Mohammad, when Islam was not spread by the edge of the sword. Islam was spread by force of arms and slaughtering infidels in the 7th century just as it is today in the 21st.
Nothing has changed. The pagan god that the Arabs called "Allah" is the same yesterday, today, and forever: probably Satan himself.
The sacraments of Islam are murder, rape, pillage, arson, making sex slaves out of young girls and generally committing mayhem as they have always been since Mohammad conquered Mecca and forced his worship, under penalty of death by beheading, on the Arabian version of Baal upon the conquered populace.
