Shahada (Declaration of Faith)
The Shahada is the foundation of Islam.
It states: “I testify that there is no deity worthy of worship except Allah, and I testify that Muhammad is the Messenger of Allah.”
Arabic transliteration: ("Ash-hadu an la ilaha illa Allah, Wa ash-hadu anna Muhammadan Rasulu-Allah.")
Meaning
The Shahada affirms: - absolute monotheism - rejection of all forms of idol worship - acceptance of divine guidance through prophets (like Muhammad, Jesus, Abraham, Moses, Noah, ...)
By sincerely affirming this belief, a person enters Islam and all their previous sins are forgiven. These Muslims are also called "Reverts" because they returned to the previous state of beeing a Muslim. (Muslims believe everybody is born as a Muslim)
Faith in Islam begins with knowledge, conviction, and sincerity.
