"'ašhadu 'al-la ilaha illa-llahu wa 'ašhadu 'anna muhammadan rasulu-llah", or "I testify that there is none worthy of worship except God and I testify that Muhammad is the Messenger of God."

The Kaaba, located in Mecca (Saudi Arabia) is the center of Islam. It is where Muslims from all over the world travel to and gather there to pray in unity.
According to Wikipedia, "A Muslim is an adherent of the religion of Islam. Literally, the word means "one who submits (to God)".
All Muslims observe Sunnah, but differences in the definition of what is and what is not Sunnah has led to the emergence of sectarian movements. The well-organised and cohesive community of Muslims who accept the Sunnah as defined within one of the traditional Maliki, Hanafi, Shafi or Hanbali madhabs are the classical Sunni Muslims. Those who fall outside of this fold are the Shia Muslims, though often thinking themselves to be Sunni Muslims.
Muslims believe that there is only one God, translated in Arabic as Allah. Muslims also believe that Islam existed long before Muhammad though it was not called Islam until the revelation of Surah al-Maeda. Muslims believe that this religion had evolved with time from the time of Adam until the time of Muhammad and was completed with the revelation of verse 3 of Surah al-Maeda:
This day have I perfected your religion for you, completed My favour upon you, and have chosen for you Islam as your religion.
The Qur'an describes many Biblical prophets and messengers as Muslim: Adam, Noah, Moses and Jesus and his apostles. The Qur'an states that these men were Muslims because they submitted to God, preached his message and upheld his values.
