Whoever claims that he did not nominate his successor...
Whoever claims that he did not nominate his successor, is suggesting that he launched the frail vessel of Islam on turbulent seas without a compass, without a rudder, without an anchor and without a captain, and left it completely at the mercy of wind and wave. It is to presuppose that he was unmindful of the most vital interests of the Muslim umma, and that he was heedless of the welfare of the generations of Muslims yet to come.
Such “heedlessness” on his part could have had three possible reasons, viz., (a) All members of the Muslim umma had become intelligent, wise, God-fearing and God-loving; and each of them had acquired perfect knowledge of the interpretation of Qur’an. Also, every individual was equal, in every respect, of every other individual. It was impossible for Satan to tempt or to mislead any of them. Therefore, Muhammad could leave the duty of selecting and appointing his successor to blind chance.
He could take comfort in the thought that whoever was made the leader of the community by the drift of events, would be the right man; and the government of Medina and the community of the faithful, both could be entrusted to his care. But such was not and could not be the case. It is impossible even for two individuals to be identical in ability, character and temperament. Muhammad knew that all the Arabs who had accepted Islam, were not necessarily sincere Muslims.
Among them, there was a very large number of “hypocrites” or “nominal Muslims.” Their presence in Medina is attested by Qur’an itself. They professed Islam outwardly but at heart they remained pagans. They were the enemies of Muhammad, of Islam, and of the State he had founded. They constituted a “fifth column” of paganism in Medina, ready to seize the first opportunity to subvert Islam.
If Muhammad were to leave the new State without a head, he would, in effect, place in the hands of these ideological saboteurs, the very weapons with which they would destroy it. Muhammad knew all this, and he died, not suddenly, but after a protracted illness. He had abundant time to attend to the important affairs of State the most important of which was the selection and nomination of his own successor.
One thing he could not do, was to abandon his government, which was the Kingdom of Heaven on Earth, to the care of some unknown favorite of fortune or some swashbuckling adventurer. (b) Mohammed did not really love Islam. He was animated only by personal ambition.
