During the Farewell Pilgrimage, which was made in the last days of the Prophet’s (s) lifetime, God revealed to him, ‘…This day have I perfected your religion for you, completed My favour upon you, and have chosen for you Islam as your religion…’ [344] It is the issue of Divine Leadership which completes the religion.
The Prophet (s) did not die until he (s) clarified the knowledge of their religion for them, showed them their way, put them on the straight path, established Ali (s) as their Guide and Divine Leader, and stated whatever the people needed. Whoever thinks that God has not completed His Religion has, in fact, denied God’s Book. Whoever denies God’s Book is an atheist.
Are the people aware of the degree and worth of Divine Leadership and its rank amongst the nation so that their choosing a leader be acceptable? Divine Leadership is much more magnificent, nobler in status, higher in position and much more deep-rooted than to be understood by the intellect or views of the people so that they can elect a leader by themselves.
