Shahada

The Shahada is an Islamicoath and creed, and one of the Five Pillars of Islam and part of the adhan. It reads: "I bear witness that there is no god but God, and I bear witness that Muhammad is the Messenger of God." The Shahada declares belief in the oneness (tawhid) of God and the acceptance of Muhammad as God's messenger. Some Shia Muslims also include a statement of belief in the wilayat of Ali, but they do not consider it obligatory for converting to Islam.

A single honest recitation of the Shahada is all that is required for a person to become a Muslim according to most traditional schools.
