The Shahada is the first and most important pillar of Islam. It is the foundational statement of faith that brings a person into the fold of Islam.
The Shahada is a simple but profound declaration:
"Ashhadu an la ilaha illa Allah, wa ashhadu anna Muhammadan Rasul Allah."
Translation: "I bear witness that there is no god but Allah, and I bear witness that Muhammad is the Messenger of Allah."
