Right from the start, violent jihad served as the engine of Islam under the command and supervision of Muhammad himself. To understand how quickly Islam spread around the world, we must see the timeline of Islam.
After Muhammad’s death in 632 A.D., his friend Abu Bakr was named caliph and ruler of the Islamic community, or Ummah. Muhammad’s followers in a short time occupied a vast geographic area; conversion to Islam was heightened by Islamic missionaries, who intermingled with local populations to promulgate the Islamic teachings. It resulted in Islam’s spread outward from Mecca toward both the Atlantic and Pacific Oceans and the creation of the Muslim world.
In no time at all, Islam spread like a pandemic. Once it attacked the mind of its victims, this debilitating disease was capable of transforming them into helpless pawns that had no choice but to execute what they were directed to do.
Here is the truth, as bitter as it may be. Islam is the culprit. Islam is anything but a religion of peace. Violence is at the core of Islam. Violence is institutionalized in the Muslim’s holy book, the Qur’an, in many verses:
Qur’an: 9:5: “Fight and kill the disbelievers wherever you find them, take them captive, harass them, lie in wait and ambush them using every stratagem of war.”
Qur’an: 9:112: “The Believers fight in Allah’s cause; they slay and are slain, kill and are killed.”
