Shahada
In Islamic theology, the Shahada is the declaration of faith. When stated aloud, one is considered to have officially declared oneself a convert to Islam. In English, the Shahada is "I believe that there is One God, and Muhammad is his messenger (prophet)". In transliterated Arabic, the Shahada is "Ashadu la illaha il Allah, wa ash-hadu anna Muhammadur rasul Allah".It is considered correct to refer to previous figures, such as Jesus (in Arabic, Isa) as prophets (rasul), and some groups (notably certain Sufi mystics) will amend the declaration to mention prior prophets whose names are found in the Qur'an.
