Central to the teachings of Prophet Muhammad like all other Prophets is the message of pure monotheism, where he called people to abandon idolatry and worship only one God, asserting that this is the path to salvation. Monotheism is more than just a doctrine. It is the secret of all forms of human success. To believe in one God is to give true expression to human nature. That is why this faith lodges itself in the depths of the human psyche. He stressed the importance of moral elevation and the development of a righteous character, encouraging individuals to translate their beliefs into actionable good deeds. Moreover, his teachings highlighted the significance of preparing for the Hereafter, focusing people's attention on eternal matters rather than temporary worldly concerns. In conclusion, the teachings of Prophet Muhammad centred on monotheism, moral integrity, compassion, and the preparation for the Hereafter, guiding humanity towards a life of righteousness and peace.
