The bulk of material and explanations are overwhelming, so this paper would simply come out to be a summary of what has been explored and declared by several religious scholars.
The first difference is: Muhammad was the prophet of war; but Jesus is the Prince of Peace. Muhammad adheres to Jihad, a holy or religious war. Second, Muhammad's disciples killed for the faith while Jesus' disciples were killed for their faith. Moreover, Muhammad promoted persecution against the "infidels" while Jesus forgave and converted the chief persecutor. In this case, Muhammad was the taker of life while Christ was the giver of life (John 10:27-28). In addition, Muhammad and his fellow warriors murdered thousands while Jesus murdered no one but saved many. Also, Muhammad's method was compulsion while Jesus' aim was voluntary conversion.
They are so different because Muhammad practiced force while Jesus preached faith. Muhammad was a warrior while Jesus is a deliverer. Also, Muhammad conquered his enemies with the sword but Christ conquered his enemies with another kind of sword, the sword of the Spirit which is the Word of God. In addition, Muhammad said to the masses, "Convert or die!" but Jesus said, "Believe and live!" As a natural warrior, Muhammad was swift to shed blood but Jesus as the sacrifice shed His own blood for the salvation of many. Muhammad preached "Death to the infidels!" but Jesus prayed "Father, forgive them, for they know not what they do". Muhammad declared a holy war (Jihad) against infidels, however, Jesus achieved a holy victory on Calvary's cross and His followers share in that victory. In addition, Muhammad constrained people by conquest but Jesus constrained people by love.
In guise of religion, modern terrorists derive their inspiration from Muhammad and carry out their despicable atrocities in the name of his god; however, Christians derive their inspiration from the One who said, "Blessed are the peacemakers". Moreover, modern day disciples of Muhammad respond to the terrorist attacks by cheering in the streets, while modern day Disciples of Christ are deeply grieved at past atrocities carried out by those who were "Christians" in name only like the Crusades, the Spanish Inquisition, etc. Truth is, many Muslims are peaceful and peace-loving because they do not strictly follow the teachings of their founder, on the other hand, many Christians are peaceful and peace-loving because they do strictly follow the teachings of their Founder. Muhammad said the Qur'an is authoritative only in Arabic, and only in his dialect but The Bible is authoritative in many languages around the world, for God knows all things and can inspire His Word in more than one language.
In matters regarding music, Muhammad hated it, but Jesus and His disciples sang hymns, and the Apostles commanded the Lord's Church to sing. With regards to religious leaders, Muhammad allowed that a Mullah, Imam, or Mufti of Islam can be a terrorist and a moral animal like Osama bin Laden, however, the Bible requires that a leader in the Church of the Jesus Christ must be above reproach, and when this is not true, Christians demand such a fallen leader to be removed from leadership. In addition, Islam calls on its followers
