The farewell speech of the Prophet Muhammad was directed to all humankind at all times and for all generations. He laid down the foundation of morality, justice, equality, brotherhood, and accountability. He abolished economic exploitation and human enslavement. In his speeches on liberty, he preached against the institution of slavery. When he witnessed the slave beating episode as reported in Bukhari (2000), The Prophet demonstrated one of the rare instance of humane leadership by letting Abu Mas’ud Ansari, the accused in this instance that only Allah has ‘power and control over human beings’. This served as a powerful lesson to him awakening his conscience to the realization that indeed, he was doing something very wrong. The fact that he let go of the slave by referring to Muhammad that he let the slave go because of his intervention is to show the power of communicative skills of the Prophet. He did not speak harshly or threateningly, rather he used speech in such a subtle way as to prick the conscience of people. This is what most leaders do not do today. This study then serve as the panacea for future leaders who want to rule spiritually or secularly. Communicative tactics should be the first consideration for any leader. It is with it that you either make or mar. He has set the tone for interpersonal communicative interaction especially in the case of conflict resolution. Liberty , according to Muhammad did not mean carrying a large army to invade your enemy. Rather, it was the management of speech delivery.
