The first shahada promotes the essential unity of the faith, proclaiming that there is no god but God. The Tawhid, which is the prayer that states "no god but God" is a major component of the Islamic faith, for it asserts the monotheistic aspect of Islam, promoting unity of God as the source of existence. The second shahada demonstrates God’s essential mercy. This prayer proclaims Muhammad as the last prophet, and it uses Muhammad as the prime example of guidance for all Muslims. Muhammad received revelation that was distorted by earlier communities, such as Jewish and Christian societies; Muhammad was the recipient of the Quran’s guidance himself and now is bearer of this guidance for the rest of the Muslim community throughout history.
