Did prophet muhammed spread islam by the sword?

When Muhammad and his followers were about to attack Mecca to subjugate it to Islam, his adherents arrested Abu Sufyan, one of Mecca’s inhabitants. They brought him to Muhammad. Muhammad told him: "Woe to you, O Abu Sufyan. Is it not time for you to realize that there is no God but the only God?" Abu Sufyan answered: "I do believe that." Muhammad then said to him: "Woe to you, O Abu Sufyan. Is it not time for you to know that I am the apostle of God?" Abu Sufyan answered: "By God, O Muhammad, of this there is doubt in my soul." The ’Abbas who was present with Muhammad told Abu Sufyan: "Woe to you! Accept Islam and testify that Muhammad is the apostle of God before your neck is cut off by the sword." Thus he professed the faith of Islam and became a Muslim.
