Rightly Guided Caliphs - The Caliphate

The Rightly Guided Caliphs

Upon the death of the Prophet, Abu Bakr, the friend of the Prophet and the first adult male to embrace Islam, became caliph. Abu Bakr ruled for two years to be succeeded by 'Umar who was caliph for a decade and during whose rule Islam spread extensively east and west conquering the Persian empire, Syria and Egypt. It was 'Umar who marched on foot at the end of the Muslim army into Jerusalem and ordered the protection of Christian sites. 'Umar also established the first public treasury and a sophisticated financial administration. He established many of the basic practices of Islamic government.
