When Hazrat Abu Bakr Siddeeq was elected as the chairperson of the Khilaafah he delivered the following sermon to the public:
My brothers and loved ones!
I have been elected as your Khalifah. Although I was not better than you even then I have been elected as your leader but my leadership is not like that of Qaisar and Kisra (kings) that none can interrupt in my decisions. Bear in mind that the strong among you is weak in my view until I give the right to the weak from him and the weak of you is strong in my view until I strive for his right, and one more thing, never lag behind from making Jihaad and do not abandon this spirit. Remember, a nation that abandons Jihaad becomes disgraced in the world. And truthfulness and righteousness is a trust, and lying and wrongdoing is unfaithfulness. It’s obligatory upon you to follow me for as long as I remain obedient to Allah and His Messenger, and when you do not find me as such then reject my followership with no hesitation, for then there will be no obligation upon you to follow me. It is your duty to guide me on the straight path.
(Tareekhe Islam p. 130)
Hazrat Abu Bakr – may Allah be pleased with him – was elected as the Khalifah by the consensual agreement of the Muslims and the only objective he had was to establish the command of Allah and His Messenger – may Allah send peace and blessings upon him. There was no worldly greed, and he considered himself as a slave of Allah and His Messenger, and had given the people freedom not to follow the Khalifah in the anti-Shariah actions.
