He has begun to prepare forces for the invasion of the Persian and Roman empires, since their rulers spat upon the exhortations of the prophet to embrace Islam. Abu Bakr swiftly put down revolts of several upstart prophets and tribes claiming to be the true spiritual guardians of Islam. The Ansar (or helpers), followers of Islam originating in Medinah, promptly chose Abu Bakr, one of the senior companions ( Sahabi), and also father-in-law, of Muhammad, as his Successor (which is Khalifa, or Caliph, in Arabic), passing over Ali, Muhammad's cousin and brother-in-law. Rise of Islam - Muhammad, the prophet of Islam, passed away on August 8, 632. 633 is truly an exciting time for mankind. Remnants of paganism remain in England and East Africa, and many nomadic tribes have yet to settle down. Islam has not yet spread beyond the Arabian Peninsula, but the Arab tribes are numerous and zealous to fight for their new faith.
