I know that the Prophet is strong, so is he the strongest man?

Allah Almighty bestowed upon His Prophet Muhammad, peace and blessings be upon him, immense and tremendous strength, encompassing both physical and spiritual power. His spiritual strength was evident in his life and his influence on others, such as his judgment among Quraysh regarding the placement of the Black Stone before his prophethood. As for his physical strength, it was demonstrated in his ability to shatter a great rock on the Day of the Trench, his wrestling with Rukana, and his ability to be with eleven wives at one time. Anas reported that he was given the strength of thirty men, and in another narration, forty.
