While Muslims worship the same God as Jews and Christians, it is important to understand that Muslims are extremely strict in their monotheism. Muslims do not presume to give God any human characteristics, associate God with human behaviors, or associate any kind of family, children, or deities with God. “There is only one God” is a central tenet of the Muslims faith. Muslims do not believe in the Christian trinity, or in God taking human form as also happens in many eastern religions. God does not get hungry, tired, or sleepy, and he certainly does not have children.
However, this leads to another common misconception about Islam, that Muslims do not believe in Jesus. In fact, Jesus is an extremely important figure in Islam. However, Muslims do not view Jesus as the son of God or as any sort of deity. To Muslims, Jesus is a prophet of God, like the many others before him such as Moses, Noah, or Job. Muslims believe in the immaculate conception and in Jesus' miracles. However, these are all considered works of an all-powerful God, and not signs that Jesus was divine himself. Like many Christians, Muslims are also awaiting the second-coming of Jesus. Islam considers Jesus one of the greatest of God's prophets to humankind.
It is also important to understand that Muslims do not worship Muhammad in any way. In fact, Muslims do not even consider that Muhammad is the “founder” of Islam. Muhammad was the bearer of God's message, through the Quran. Muslims consider that this message was sent by God to his people through the many prophets that came before him, including Abraham, Moses, and Jesus. Muhammad was simply the last of God's messengers to mankind. However, Muslims seek to emulate Muhammad's example both through his sayings and by the example he set for the people that witnessed him in life. One should understand that this practice is not related to any kind of divinity that is associated with the prophet Muhammad. Rather, it is an act of sincere emulation of a man that Muslims consider to be the best example of how to practice Islam correctly.
