1Sahil B = ""The Prophet died without appointing a Khalif or successor. The Shia school of thought maintains that although direct Divine inspiration ceased at the Prophet’s death, the need of Divine guidance continued and this could not be left merely to millions of mortal men, subject to the whims and gusts of passion and material necessity, capable of being momentarily but tragically misled by greed, by oratory, or by the sudden desire for material advantage. These dangers were manifest in the period immediately following our Holy Prophet’s death. Muhammad had been, as I have shown, both a temporal and a spiritual sovereign. The Khalif or successor of the Prophet was to succeed him in both these capacities; he was to be both Emir-al-Momenin or “commander of the true believers” and Imam-al-Muslimin or “spiritual chief of the devout.” Perhaps an analogy from the Latin, Western world will make this clearer: he would be Supreme Pontiff as well as Imperator or temporal ruler.Ali, the Prophet’s cousin and son-in-law, the husband of his beloved and only surviving child, Fatima, his first convert, his bold champion in many a war, who the Prophet in his lifetime said would be to him as Aaron was to Moses, his brother and right-hand man, in the veins of whose descendants the Prophet’s own blood would flow, appeared destined to be that true successor; and such had been the general expectation of Islam. The Shias have therefore always held that after the Prophet’s death, Divine power, guidance and leadership manifested themselves in Hazrat Ali as the first Imam or spiritual chief of the devout. The Sunnis, however, consider him the fourth in the succession of Khalifs to temporal power."-World Enough and Time, Aga Khan III"
